wrinkle problem

[1tuff71]

Ok so the PO painted the truck black ( swore I'd never own another black truck ) and I boggered up the tailgate working off of it and went to " touch it up " with some rattle can Rust-Oleum. I did a test spot and it wrinkled so tried a couple other types and it did the same thing. Can anyone tell me what type paint is on my truck that would do this and what type is safe to use without the wrinkling ??????? BTW I used to live in Calif and where the truck was bought and I think they have rules there as to what type of paint you can use.

Any pictures of the "wrinkling"?

If you are spraying a laqure type paint and the old paint is enamel you could have what you describe.

Normally the cure to a wrinkle in the finish [or frying as it is sometimes called in the body shops]is 80 grit sandpaper. Strip it down with 80 then go back and sand then with 180 or 220 grit then clean it real well then spray 2 to 3 coats of epoxy primer then spray 2 to 3 coats of high build primer. Barring any filler work that needed to be done you should be ready for a finish color. About 75% of the time or greater if you sand off the wrinkle and try to spray some thing on it it may lay down ok for a short while with the primer but then when the paint coat hits it it will go ape poop crazy and fry all over again. I know it may sound frustrating and difficult but this is sometimes some work that is not fun and it needs some effort to get decent results. Good luck and happy sanding. Jim
