So working upside-down can be a challenge but we're going to show you a
quick tip on how we can accomplish this without much effort.
Alright guys so replicating this bead can be a little bit of a challenge.
Again we're working with material upside down so I want to give you a quick tip on how
to replicate this with a little bit of ease. We're gonna take a standard mud
spreader first right and then we're actually going to cut a notch in it and
then in this case here to replicate the look that I'm going for I used a hole
punch and actually created a little bit of a dimple in that spreader and where
this is going to apply is when I'm actually putting it on that wheel arch
it's gonna act as a guide and that's going to make my bead for me and remove
any excess material and this is simply done by we're gonna put the material on
the surface first and then we're gonna drag the spreader along keeping it at a
consistent angle as we go. We don't want to tip it forward backwards upside down
we want to stay consistent perpendicular to the surface so that we get a nice
square bead all the way around that wheel arch. So we're gonna do it on this
flat panel here so you guys can see it a little bit easier but again you can use
this same practice on that wheel arch. We're gonna use our heavy body product
heavy body seam sealer 8308. We want to start as always by equalizing
our two part cartridges upright into a paper towel. After that we're going to
apply our static mixing nozzle and once we have the ring secured we want to
actually dispense a little bit of material out onto a mixing board or into
that paper towel. Usually we say two to three inches we just want to make sure
that we've got adequate mix coming down the nozzle before we dispense it out on
the vehicle. Once we've equalized it let's get
started on the car itself.
So what I've done is I've just run a bead right along that edge so again
we're doing this on a flat surface so you can see it a little easier picture
this kind of upside down. If I feel like I need a little bit more material to be
put out I'm gonna go ahead and run another bead right over the top of the
one that I just laid. Once I feel like I have enough material on there we're
gonna take our spreader and we're gonna use that notched edge as our guide and
we're gonna drag it along we're gonna create that bead. Now this is doing a
couple things. When we dispense the material we're pushing it onto the
surface so we got good adhesion. When we use the spreader we're also forcing it
into the surface yet again and we're creating a nice clean edge on the seal.
Now if you want you can come back in here while it's still wet we can clean
up this excess material without disturbing that edge. You could also wait
until this is cured and you could sand that out to a smooth finish
so that way after its painted all we have is this nice smooth bead on that
wheel arch. So that's it for today's bead. If you want more information on any
