In my previous posts (click "...Tips" tag at the bottom of this post), I described the crazing problem that I experienced.
Well, I am now doubting myself and my results. There is a whole TRF thread on this primer and nobody has complained about the problems I saw. In fact, they praise the product. My problem remains a mystery. I waited plenty of time between coats, it wasn't humid and the crazing happened with primer-over-primer and primer-over-Fill'n'Finish. I have posed the issue to the TRF crowd and will see if there are any revelations.
