I'm getting ready to pull my gas tanks from my sv and sealing them, I've read all I can find on the forum about this and pretty much know what I'm going to do. I'm going to use por15 sealer kit. My question is, does this sealer hold up over time, no cracking, peeling, clogged gas lines, etc? I've always been real skeptical about putting anything in a gas tank other than gas. I don't want to have to pull the things out of the car again 5 years down the road and repeat the sealing process. I also realize that initial preperation is the key factor here.
