this is back and he's actually working eric montague on his
knees nonetheless vacuuming cleanup work i told you some people do
their best work on their knees knees that's right
yeah it's not you hopefully no this is not your best work okay good
we've had a coatings failure eric loves coatings failures
don't you well i don't love them well they do geek out
yeah yeah yeah so we had a coating spray let's show it to you this had water sit
on it for weeks and i didn't ever attend that but
it accelerated it so watch this whole piece that is paint and it
ain't supposed to do that now i noticed it and it's all along the
side here where it set in the water for a week
because we we had water coming and there was been a lot of sand and moisture on
it so it held water against it and tell me what you think happened here
disbandment disabundment why um well near as i can tell just looking
at it which is exactly what i always do the
the ross the the rust doctor has adhered to a
layer of surface scale rust right right and that rust was loose
the rust doctor attached to that but couldn't encapsulate it and go past it
and adhere to the steel uh rust doctor is
fosteric acid with a little bit of sticky stuff in it too
it's very common rust converter is what you'll hear it talked about
we use rust doctor which is a brand of rust inverter on this so that's what
he's mentioning and then what happened is is the epoxy
the epoxy was laying on top right it
it adhered to the rust doctor so this area is the rust doctor yeah this
black here and see here this red stain here
yeah this is where the rust doctor um converted it but it wasn't an
intermediate layer so it it wasn't keeping the the
epoxy from it uh sitting directly on the steel
but it didn't have a good enough surface adhesion
enough surface roughness to actually lock
onto the steel so the rust doctor failed yeah the rust doctor failed in in two
different methods you see here you've got a you've got
this black here and then you've got this this is this is the rust doctor doing
its thing right correctly yeah this is this is a correct
conversion all right we're here it didn't convert all the way it didn't
convert it and so we may not have put enough on or we may have had too much
loose rust still on we've pressure washed this surface
but there's no profile to it right and see here
in fact i can actually hear and feel it yeah you can hear that when you feel
that up this is still going back i mean this is
continuing on and let me go get a needle down let's just see how much
we can take off okay i can get a scraper too that's your inspection tool
that is eric montague's world famous scraper with teeth that looks like you
made that yourself i did yeah look at the braided handle oh yeah
fancy and oh and the leather pouch leather
form fit oh my god i'm that guy you're that geek that's totally you man
so this is usually what i do at work yeah look at really expensive coatings
and tear them off yep yeah this is not gonna hold this is
not done adequately see here it's starting to adhere again yeah
and we did measure the the paint here and it was
what'd you say the coating was between 10 and 19 mils 19.
and that's mills so when we say how thick paint is in mills we're actually
talking about thousands of an inch and see
i found the limit of its being soft that's about it it is weird this right
around that well i think it goes on down the boat
both directions where the water was
i'm not feeling it soft that is right up to the weld sink there's a weld
scene that runs right along here it's a plate of steel that comes up it divides
this tank from the tank over there
so it like the the roughness of the weld well it's probably that mechanical
adhesion from it being ground right there right and
that that increases the surface profile just enough
and that's all it needs is just a little bit more advantage so you think we'll
just grind this back down to bare steel and skip the rust doctor this
time i i would i would just i mean we may
have ended up doing the whole deck down here that way well and you
know doug here it's not an issue to be cosmetic
yeah and with that coal tar
he really likes being static so this would be a good
place for it but what it what it probably did is as the water was sitting
here it found a holiday in the coating yeah
to get the water so now you've got water intrusion
so now it's getting underneath the coating or behind the coating
right um and then once that happens then it's just
you know it's just literally floating bubbling up the
coat spreading out yeah i'm really happy i didn't use rust doctor on the hull
outside i wouldn't want to be doing that over
again this in here no big deal and coal tar is the product we put on
the outside of the boat it's it's it really is a lot it sounds like
it's almost a tar but it's a has an epoxy mixture into it now so they
call it koltar epoxy and it goes on like tar it's heavy and
thick and i've had no problem with it doing
this but i have had problems over the the rust
doctor a little bit and uh where especially where i put the
rest out there on too heavy it didn't like that in the engine room
and so it's not a bad product but it's not a miracle cure the best thing
you can always do is sandblast get a profile on it even hand
grinding get a profile on it and then go directly over that with a
coating not a paint what are you marking um impact damage oh impact damage
yeah so i'm wondering what we should do with the rest of it in here you think
running neva over the whole thing is finding anything that's loose so so like
right here i'm not gonna sand blast in here no
no no i i don't think it's needed i think what we should do is just do
spot treatments with a needle gun right um because the needle gun will reach
places where the grinder's not right grinder would probably get us as
good a surface profile but with the needle gun i mean it's
noisy is all get out but well let's try it on one of these spots
you yeah here we go
i could probably take the whole floor off of myself yeah and
and i don't think we need to do that i just like
this area over here doug where you weld it on a clip yeah so
we'll need a gun right here you run it
let's see that's the advantage of the needle gun we can reach you yeah you get
into the weird places that's why the industry has such a
love-hate relationship with these machines i
like the needler it's just something satisfying about running
does the needle gun add any profile to the steel there
oh yeah i mean a little bit not not like sand blasting or anything
no but see what we're doing is see how it's actually turning
i mean you're getting you're getting impacts and those pock marks
and it is creating some some mechanical tooth there
right but a grinder would be preferred in an open area like sure sure i mean
places we could hit with a grinder it would be better to use a grinder right
but spots like this you're never going to get a grenade
you're going to get a grinder in there i mean maybe a die grinder with a bird bit
but that just looks like a broken bird bit to me
yeah yeah
okay what's happening is as we hit areas next to spots it's moving the steel
enough that we're going to actually just keep loosening it so what we should do
is switch to manual scraper yeah
and the grinder will cut that paint away i can see where a grinder would be
better because it would not only taper the paint in and get a
feathered edge all right let's see here but it won't
it's where it's breaking right along the edge where i'm scraping
right so that's that's tightly here yeah so we don't need to taste that anymore
there's a spot that's still loose yeah if we go at a right angle to it and we
can kind of cut that off and then find out okay what's loose what's
not i mean this area here in the center where it probably wasn't submerged in
water not for very long it doesn't seem very loose but the
closer we get out to the peripheral edges that's where all the
water take was yeah
that actually sounds pretty good yeah see
that's just a that's just a blob of paint blob of paint
but what i'm doing is i'm actually
feeling
no that's actually adhered fairly well
so we go over the whole thing with a scraper and find the problem
yeah needle and grind where we do yeah see this
this whole area i don't i don't see anything that's loose yeah
all right well thanks that's been very helpful not a problem oh it's a
lovely cool morning out for for july
anyway
be thankful for all the struggles you go through they make you stronger
wiser and humble don't let it break you let it make you
yes i scored a chisel helped put the fancy little measurement marks in it but
this is a wonderful tool i'll put a link in the description if you want to get
one for yourself and it's off amazon so i get a
commission for selling it to you thank you for supporting sv seeker i
suppose i should give the commission to eric but
he's a board member on our non-profit so yeah eric doesn't get it
and the chest foundation is the name of the non-profit
uh it's just betsy uh and eric and richard day
and they take care of the administration of it it's a 501c3 in the united states
that means you can donate money to it take it off your taxes
you got to donate a lot of money to something like that but anyway it's a
it's a non-profit organization and that organization
figures out how to give the money to researchers that need money to come on
this boat and they lease this boat for a dollar a
year along with the volunteer crew that's how
the whole thing works so if you want to donate to that you can
there's already a fund set up for it there's i don't know
four or five thousand dollars in there now but we'll start asking for money for
that later on and you'll get to see how it gets spent
on you know uh maybe water testing equipment or to get
some researcher out to the boat uh or maybe nets for their work you know
whatever it may be that's what that money is for
and all this damage seems to be really confined to the area where water's set
on this for a long time and i'm looking at some really thin
paint here in places so i think it was an application there as
much as anything else water gets through one spot spreads in
fact when i chip this up sometimes i see a puddle of water underneath it so
you know it's obvious to know what went wrong
i'm not trying to get this smooth i'm actually trying to get it rough
i want tooth in the steel there so the paint can grab onto something
and i'm feathering a little bit out here on the edge so the transition isn't that
harsh
apparently i'm making a lot of dust in the back room
that's the nest alarm in the aft cabin
when we put those hydraulic lines in i was afraid we would not be able to get
this out but it looks like you just make it
these are our water tanks and i want to put a couple more coats of paint on here
just to make sure they're sealed up good and it's the same paint it's
a mirror lock two which is a potable water tank as well as
a great paint overall the corners got glue on
them from having glued the corner of the gasket together so i understand that
mistake but i don't know what made it stick out here
where the paint was even dry maybe the paint wasn't dry
i'm going to replace them with that kind of gasket but i think i'm going to
use butyl tape this next time see how that does
just coming along doing the difficult spots and the
spots that i had to grind first the problem is that
i gotta have it eighty percent humidity and i gotta stop when it hits 90.
so i could paint from 10 30 to 12
30.
that's it floors back in and i'm done it's hot in here it's a hot day out
today in oklahoma and the damage has been repaired and the
tanks are in great shape so we're done underneath the floor so
what did you make today send us your photos enjoy these get
inspired by a lot of people's great projects and it doesn't matter if it's a
bird house or you're building a rocket ship to go
to mars okay creativity is creativity you do it on your level
and you be proud of it dammit
do
you
