Strange oil paint problem

[Mongo Mel]

Hi,
I had something strange happen recently and was wondering if anyone else had encountered this before.
I was painting the display sample of a garage kit figure being produced by two guys in my model club. The piece was cleaned and primed (Krylon) with plenty of time to cure. When I began painting with oils, I quickly noticed that the oils were actually drying as I was spreading them across the piece.
No kidding...they were thickening and beginning to dry that fast! The brush was sticking in the paint and there were clumps forming.
The primer and paints were the same ones I've used for everything else I've painted and it was happening with several different colors so I don't believe it was the paint.
I asked one of the manufacturer guys if anyone else had had this problem too. He said no one mentioned anything to him but that they hadn't done too many other kits yet.
After stripping everything and repriming, I undercoated the pieces with a spray can of Krylon acrylic paint and no more problem.
So, I was wondering if anyone else had ever experienced this problem.
Thanks in advance
Craig

I have seen this sort of problem once before, on a garage kit of an artillery piece. I think it is something about the chemical formula of the casting material. The gun was alleged to be resin but nobody is sure what it is. If your piece is in resin from a reliable source I don't know what it could be.--

A friend had this problem once. He stripped and scrubbed it with soap and water, primed and re-painted it. After a few weeks the paint started lifting. He re-stripped it, washed it again, and then primed it with a top of the line automotive primer. He said the automotive primer really sealed it and he never had a problem after that.

Hi guys,
Thanks for the feedback.
Steve, I can only say that the resin was the same that they've been using in the past for their other kits. It is an unusual color from any other resin kits I've ever seen.
Gary, the first primer was automotive but the second time I used Alclad primer sprayed through my airbrush. That may have helped too.
Thanks again,
Craig
