That bubbling is a reaction to what was under it, or possibly thinner bubbles from the outer layer drying faster than the lower layers. You get them with real automotive paint if you dont allow enough flash time. Least I did..lol.
Also, those scratches are the paint chipping off the substrate from the force of the attempt, not a scratch IMO. Im sure in either case, getting the proper temps and prep would fix it.
The bubbling explanation makes sense.. I did go over the whole area with mineral spirits on a rag, but maybe the rag wasn't clean or I didn't do it long enough.
As for the scratches, yes that is the paint coming off the metal/paint/whatever underneath it. But whether I use my fingernail to dig in, then pull down and remove it, or slash it with a screwdriver, it still removes the paint. I try my fingernail test on the original door paint, and on my dart, and the fingernail does nothing. Oh well there's still time for it to dry.
