Hi People my Appologies I am not a Hotroder but a Ford Prober I was wondering if you spray painting experts could help me with a very annoying Paint problem heres the story-

1 rubbed down my roof keying the original factory laquer then recoated in base coat then non poisionus 2-pac laquer about 6 weeks ago the roof came up very nice.

2.had to tape over my sunroof opening with a black bag 2 weeks later to remove and clean the paint from my sunroof frame, When removing the masking tape the laquer lifted with it a strip about 1inch wide by 1.5 inches long

3. read up on spot repairing on Internet and attempted to repair damaged section without rubbing down whole roof and respraying the whole lot again.

4.flatened down the damaged bit with various grades of paper then sprayed some base coat onto it, The edge around the repair which was feathered out began to wrinkle just the edge .

5. allowed it to dry then rubbed down again being very fussy this time with prep work and cleaning the area with panel wipe. tryed again same ***** happened.

6. rubbed down again and sprayed some of my non poisinuss laquer over the repair to seal it in.

7. 24 hours later gently rubbed the laquer flat with 1200 grade and cleaned the area, Sprayed some base coat over repair then 2-3 coats later the new laquered edge around repair began to wrinkle the old edge on original repair beneath was fine

What the hell is going on I give the base coat time to surface dry 10-15 mins between coats in a very warm dry workshop, What I cant understand is I have spot repaired other smaller blemishes which were paint scratches bellow laquer on other parts of roof without this wrinkling problem. Bearing in mind they were spot repaired over laquer without multiple paint edges tapered out. Is it something to do with having rubbed down through 4 differnet layers of paint on the roof which is exposing 2 differnt 2-pac and base coat finishes

I am getting very ****** of now this car has been a knightmare with everything I have done to it going tits up at some point or another, I have resprayed my fiesta's with body kits in the past using good old celluloiuse with no problems what so ever I wish she was a gloss colour and not this mettalic carry on.
