Recently, I've suddenly started having problems with the washes causing the acrylics to pucker and lift, and I get left with alligator skin in some spots, or worse; the acrylic paint comes away altogether and I'm left with a spot I have to repair and/or hide. I generally use Pledge as an overcoat between laying down acrylics and applying oils.
Like I said, it's never been an issue until very recently, and there are only two things I can think of that have changed.
The first is that I'm using a different brand of turpentine to dilute the oils because the brand I was using in Japan is not available in the US. It does appears to be stronger stuff, but I was always under the impression turpentine shouldn't affect acrylics.
The second thing is that I switched from polyester-acrylic primer to regular automotive primer recently because it gave me much better adhesion. I thought that the turps might be affecting the primer so I switched again to Mr Surfacer in a rattle can. After a few tests it seemed like the Mr Surfacer remained pretty bullet proof, and from what I can see the turp is still loosening the acrylics without damaging the primer.
Anyone have any experience with this and can recommend a fix?
