I need to use seam sealer in the trunk. I am wondering how best to recreate it what is shown? Looks like 2 or possibly 3 different products at the bumper bracket? Looks like a runny self leveling type at the trunk floor, something thicker or stiffer, and less runny around the bracket at the tail light panel, and maybe a piece of dumb gum across the top of the triangle shaped part of the bracket at the tail light panel?
I guess the last two could be the same stuff?
Thoughts on what modern products most look like this appreciated.
It seems crazy to voluntarily turn the below into the above, lol.:
I just chiseled the old stuff from the top of my reinforcement bracket and it's plain old seam sealer. My guess is that it's all the same and the stuff on the bottom was simply smeared around for coverage.
Maybe the best method for the factory look is pretending that it's near quitting time and you have to finish this car. A good substitute may be to hold off application until you really, really, need to go to the bathroom.
Seriously, though....I'm so anal-retentive, I will most likely run some painters tape on the outer edge to peel off afterwards.
i applied a two part heavy bodied sealer over the required joints (3M 8308?).
I then put some spectrum in a undercoating gun and sprayed it at low pressure. i believe i made two passes (can't quite remember. if you do, let it dry a little between).
mask the surrounding areas. i had to do a little cleanup of some of the spatter.
i let it cure for a few weeks before epoxy, base/clear.
you'll need to experiment with the gun/pressure's to make it look like the pics i had posted. i want to say i was holding it around 1-2" from the surface. i did use a larger distance when spraying the inner quarters.
don't tape all the way in (so you don't get an edge).
Does the 3M need a special applicator gun? How easy or hard was it to work with?
one thing i learned was to do small sections at a time. for example lay a three foot bead in the seam you are trying to do. then go back with your finger (or whatever technique you use) to spread it out.
if you do short sections at a time, it will keep the material moving thru the tip. the stuff kicks pretty quickly once it hits the self mixing tip.
