I followed the lead of someone else here and decided to do some paint touchup with duplicolor paint on my white 1996 SSEi. This was my first try at auto painting, so I studiously tried to follow directions. I did all the lengthy prep work that you're supposed to do. Sanded the area first: first with 100, then 220, then with 400, then with 1000, then with 1500, then with 2000 grit paper. I washed the area. Then I used 3M paint prep to remove any contaminates. Then I masked off the area with with low adhesion house painting masking tape/paper. Then I used a duplicolor paint adhesion spray (two layers). Then I put on about 5 or 6 coats of paint, each very thin, letting it dry 5 minutes between each spray. Then I waited an hour and applied a top coat, and then 2 more top coats at 5 minute intervals. It came out looking pretty good. Even the color seems to match pretty close. I waited an hour, and then went to pull off the masking tape. Ooops!.
I really did that wrong. It came off fine in most spots, but of course in the most visible spot it "peeled off" some of the fresh new paint (like your skin peels off after a reallly bad sun burn), ripping into the paintjob.
Afterward, I read this is called "delaminating".
I'm not quite back to square one, since the "scrapes" that went all the way to the plastic are still painted over. So, I went from a big eyesore to a smaller eyesore. I guess I'll have to sand down the peeled paint zone and try again. Where did I make my mistake so that I don't repeat it? My guesses are:
1. I should have waited longer before removing the masking tape; or,
2. I should have somehow "cut" the masking tape free instead of pulling it off; or,
3. I should have used a masking tape that somehow repels paint, so that the paint would not have stuck to it in the first place. I've heard there'* something called--you guessed it--"auto masking tape". Does this prevent the problem I had?
4. I should have picked a better paint ahesion primer; or,
5. The masking tape was too close to the target paint zone.
Also, when should I start sanding down the affected area that has the paint rips? Right away while the paint is still soft, or wait till it has cured?
