Analyze This

I posted on another subject about wrinkle. Here is what it looks like on my piece. Something it reacting to the SEM plastic primer I am using as Brian was eluding to.

SEM's instructions are pretty clear as to prepping the piece, have you followed them to the letter? I've sprayed SEM a couple times and never had any problems using their wash, clean, and prep system...

I have never seen this happen that the undercoat being not fully flashed wasn't the problem. Either not fully flashed or a 1K product that is allowed to "move" when a new product is sprayed over it softening it with it's solvents.

The biggest thing that I can see is if you don't go back to clean plastic is it will more than likely do it again when you respray. If you can get it on dry enough to not lift I wouldn't think the life span would very good.

I did read and follow the tech sheet. I believe i had two problems. I had some acetone on a rag i used previously (remembered this after using a fresh one). And i was using to heavy a coat. After sanding a much larger area to remove more paint all the way down to bare plastic. I wiped dry with a clean dry rag, tacked it, sprayed adhension promoter, waited 5 minutes, sprayed a lite coat of the SEM product, waited 5 minutes (it was hot yesterday) then a heavier second coat, waited 5 minutes and finally a 3rd coat. Sanded and sprayed the basecoat silver, smoooooth. This week, on the the candy! Thanks to everyone for the help

THe Candy

Here are few shots of the Clear with SEM candy concentrate. Everybody is right, Candy is tuff to spray properly. I got some touch up work (edges & a few light areas). Should I spot sand with 600 for the touch up to stick? Or is there a better method without resanding the whole piece.
I was thinking of using my IWATA airbrush for the touch ups to better control overspray.. Thoughts? Anyone.

I highly recommend an airbrush for small sport repairs. I have done several this way and it works great.

I have also done 3 stage candy spot repairs... most people will say it is impossible, but it can be done with minimal evidence of a repair.

Are you just adding more mid-coat, or do you have to get into the base?

I am lightly sanding (800 grit) then Airbrushing with the Nason 498 clear w/SEM Candy Concentrate to blend the light spots. It's tricky but saves time sanding the whole piece and reshooting Base.
