Need painting advice...
I have a car that is in need of a paint job. My issue is while repairing a nasty and deep scratch a few years ago I ran into a major problem. After sanding smooth, I hit it with a shot of primer. Within seconds the paint underneath (or primer under the paint) bubbled. I cursed, waited for it to dry, sanded again, and tried self etching primer. Same problem. After much cursing and many tries I finally got it to look ok (still not good, but the color matches and the scratch is gone).
Now I want to paint the whole car. It needs VERY little body work (only a couple minor blemishes, and the spot I did last time needs to be re-done). There is no rust on the car, and it is very straight. Thus I believe only a bit of sanding is needed to prep most of the car.
The problem is how do I stop it from bubbling? I believe there are "sealer's" out there (probably the wrong term) that will solve this issue. But I have no idea which one.....
I have herd of 615 by Dupont. Is this the right stuff? Do I spray is first? Mix it with the primer???
Some back ground on me, just so you know my level of expertise... NONE!!
I have done a few body repairs that (in my very humble opinion) turned out well (not a pro job, but for a driveway repair by an amateur, not too bad). I have done many spray bomb touch ups that unless you know where they were you wouldn't know about them.
This is my first attempt at painting an entire car, so any other tips would be greatly appreciated.
I am going to rent a spray booth, and have read the books and watched the TV shows, and now I want to give it a try. (mainly because the car really needs paint, and I can't afford the $10 + K to get it done in a shop)
