Anybody know about or have you had the problem? I bought a can of Touch Up Pewter Gray #360260-100 paint from Airstream. The door step on my Bambi had some rust spots and nicks along the track where the rod is. So I took it off, sanded it down then primed it with Rust-Oleum Automotive primer. After it dried, I touched it up with steel wool in a few spots then sprayed the Airstream paint on. That was last Sunday afternoon. Today, (Friday), it still is a little tacky and soft. I had it outside when I painted it and moved it into and hung it up in my tool shed. It hasn't rained here. BTW I shook the can for about 3 minutes before using it.
I think the stuff is just crappy paint. I bought three cans from an Airstream dealer. The paint is thin with little solids and you're right it stays tacky. I cleaned what I sprayed off went to the big box store and found some Rustoleum that was much better and a good match.
No fog. It has been clear. Hot and dry. I cleaned it with liquid sandpaper.
Honestly, I've done this stuff a lot and never had this problem. I also painted the steel bars for my Equalizer right after and they dried completely. I used Rust-Oleum Gloss Black.
You folks on this thread have newer rigs than our 1984 but maybe this will help. But maybe your paint color is different...
I found Rustoleum #244228 "Metallic Charcoal" to be a perfect match to the dark frame and tounge paint on ours. I bought the paint in spray cans at Wallyworld. It's held up really well over two camping seasons.
I had the same problem with the airstream pewter grey paint. The paint got tackier as the day warmed but felt dry in the cool mornings. It eventually dried after several weeks.
