Problem with paint "Pettit"

Post by Marc »

Hi,
I was painting my A22 (i know it's not a CD but...You are the bests) and at some places the paint did not stick up, i do'nt know why because i dewax and use 2 times the tiners for removing the dust. I was @#$# because i put so much time for preparing the paint job.


I think i found why i got this problem. I use tack cloth just before painting and maybe the cloth leave some resin on the deck. Do you think it's the good reason?

PrepSol

Post by John R. »

It didn't stick for one of two reasons:

1) Lack of tooth due to insufficient abrasion of the underlying surface.

2)Surface contamination of the underlying surface as a result of improper prep.

Or it could have been a combination of the two.

If you used a commercially made tack rag and not a home made version the chances are next to nil it caused the problem. To prevent these type of painting problems use a top quality prep solvent specifically formulated for use in painting prep work. I always use Dupont PrepSol, nothing else. It easily removes all contaminants and waxes and leaves the surface spotless. Next,lightly wipe down the surface with a quality commercial tack rag just prior to applying your first finish coat.

Acetone, alcohol, laquer thinner and other basic solvents don't work as well as true prep formulas. There are other brands of prep formulas on the market besides the Dupont. Most major paint finish manufacturers offer a prep formula in their product line up. I've used the Dupont with all sorts of different paint systems and never had any compatibility or contamination problems. I highly recommend that product for paint work. Dupont PrepSol is available at most automotive paint suppliers/distributors that deal with Dupont products.

Sorry to hear about your problem, it is very disappointing and frustrating when a new paint finish develops problems. Follow all prep instructions to the letter, the resulting finish is no better than the care excercised in the prep work.

You didn't experience a Petit problem. Good luck on the redo.

I agree with everything John says and would add that I start every paint job with a thourough wash with a strong solution of TSP and Bleach. Rinse will and then sand and solvent wash. I have never used PrepSol but it sounds great.

Never use mineral spirits on plastic or fiberglass. It leaves an oily film that prevents adhesion.

I do not know anything about A22's. I'm sure we would all like a look. It's really the Alberg universe.
