rev up your engines, today I'm gonna show you, how you can repair plastic parts on
your car by bonding them together, now I've been welding metal parts on cars
for decades, but plastic hey try a welder on
that you'll just destroy the stuff it'll just vaporize, now with the amount of
plastic parts of modern day cars, it's a good thing that this guy has
come up with a system where you can bond the plastic back together and patch it,
tech bond solution it's a small company in Ohio and they have made a system
where you can actually patch the plastic and in the interest of fairness, I've
tried out many companies, nobody's paying me to talk about the companies, I tried
out ones see which ones are good and the ones that work, hey I'm gonna talk about
like this one, these patches kind of remind me of the old patches we used to
use on car tires, only the car tire ones had glue built into them, these don't
have any glue, to make the patch bond there's a kit, it comes with the
preparation, an activator and the glue itself, now to me it seems to make a lot
of sense that a three-part bonding process is gonna be a lot better than
just getting something like superglue and trying to glue two parts together,
this has three separate pieces, as you can see here, here's a patch I made
practicing and another patch here practicing, stuff's hard it's actually
more stiff than the plastic that it's bonding together, which I find
interesting because if you know anything about welding metal, the welds are
actually stronger than the metal they're welding together that's the strongest
part, well this plastic bonding stuff works the
same way only with plastic, here I'm gonna show you how to fix a broken part that's
crackedm first you get the poly prep the preparation, and you spray it all around
the area, then while that's drying cut a piece of the patch that's big enough to
fit over there, and as a tip, always make it a little bit bigger than where the
crack is, so it won't spread then you can get a heat gun, being a mechanic I got a
heat but you can also use your wife's hairdryer
they'll work good too and turn it on full blast,
ah it's kind of chilly this morning feels good and heat the area
you heat it for about 30 seconds and then before you put the patch on you heat that
up a little too, then you get the activator accelerator, spray the both
sides with that, then you get to actual glue in this case it's a tech mind SI
blue, put that around the area and a little on the patch and put them
together, and if you really want them to stick forever, here's a trick, flip the
piece over, turn it over, then get the activator accelerator again, spray it on
the crack, then heat it up with your hair dryer for about 30 seconds and voila you got
a nice solid patch, isn't gonna come apart, now this is just an under part
on a car that covers things up so you don't care if it looks a little bit
messy, it's totally solid now, you don't care you don't even see this it's under the car
but if you're doing a body panel like this, when you're done you fill the cracks up
sand them, prime them and then paint them and they look perfect, what you want here
is, a nice strong structural fix so it won't come apart again, cuz over the
years I've tried various types of just plain old super glue, a lot of times yeah
it'll hold it for a while, but then the crack just rips right open, you get a
patch like this, the things solid now that's actually stronger than the rest
of the plastic, so all in all these tech bond guys hey, they came up with a good idea
instead of throwing away that plastic stuff and have to buy an expensive parts
that cost hardly anything to make, but hey you can only get them from the
dealer, you can now bond the parts back together with a patch and since this is
mechanic Mondaym I'm giving away a set of this tech bond molecular bonding system
patchm to have a chance to win just place a
clean non-offensive comment on youtube comments below and a winner will be
chosen randomly by computer to get a nice plastic patching kits for
all that plastic junk on your car that breaks offm so if you never want to miss
