Hi all,
Im a newbie chevelle owner. Just picked up a 67 SS. The gray coating in my trunk comes off or turns to liquid when it gets wet. I am thinking in previous life it was not done correctly and should have been finished with some type of clear coat or urethane. It looks really good right now but its not waterproof so my question is how do i waterproof it or any advice on what direction to go here would be appreciated.

I have the gray sprinkle paint in my 1969 Chevelle I had a clear coat on top , but I make sure to wipe up the water right way. And something also I did was to put plumber putty on the inside nuts that holds on the outer trim , and taillights.

Most spray rattle can spatter paint needs to be clear coated!

That's what learned MANY years ago. It seems strange that the manufacturers of rattle can paints cannot formulate a spatter paint that will not become messy when it gets wet! When I've done the trunk of my cars with spatter paint, I HEAVILY clear coat it. But it is still necessary to dry it as soon as it gets wet.
This does not seem to be an issue with factory spatter paint. The spatter paint in the trunk of my 76 Cutlass is still in great condition. I wonder what was used by the factory???

For sure Tom! All the pros I know shoot their trunk paint, no rattle cans. I wonder if the pro paint sets up and cures that much better?

I've done what you all do, with still a minor trunk leak, so now I have bare metal to finish again. Not a good solution. I may POR the whole thing. Need to find that leak first though.

I don't know guys I seem to remember always seeing truck splatter paint on the bottom vinyl floor covering when I lifted it up. I even saw the rust with it. Whatever that stuff was it didn't offer any protection against rust and considering it is a #1 location to rust that tells me it held water.

The rattle can spatter paint belongs in the trash can. Even when cleared, it will still peel eventually. Much of it has to do with whats underneath as well. You can't just spray it and expect it to stick. The surface has to be free of rust and prepped correctly. That is where most failures occur.
I shoot reduced and catalyzed urethane paint for trunks. It never separates.
