seam sealer

i just was wondering what you guys are using for seam sealer and what would work best under paint and what works best under linex

I use the fast and firm seam sealer..I think 3m brand...not sure..but heres a good tip..spread the sealer with the gun..then get a cup of thinner and keep your finger wet and run it over the seam to smooth it out...works perfect..and you can never put too much thinner on it..just keep it wet and it will flow perfectly, then it evaporates..just be sure to let it dry for a couple days..its works best under line x ..sometimes it will crack under paint if its a lil thick and you press down on it after the paints on it..cause it will fle more than the paint

any links to get it online?

eastwood has gotta have it right?

napa, even napaonline.com RED

i didnt c it in my eastwood book

The brush on stuff that u used works best..the gun stuff can get real messy..i prefer the brush on seam sealer goes on clean looks clean not to thick and hardens very vell
