For a long time now, since the nineties, I have been using Krylon primer, after it was touted so much on this group. Lately, however, I am finding they have changed the mixture and it is not as good as it was. Sometimes now hotter finishes seem to craze or affect it- it used to be bulletproof for ANY finish.
I have found Duplicolor auto primer to be even worse. It seems to be some sort of acrylic now. Hot finishes like cellulose lacquers definitely affect it.
What are other people using these days other than hobby shop primers (which are very expensive and not that good, in my experience)? I like something with a lot of filler so it can cover scratches and minor flaws.
I gripe- paints that say lacquer, but do not note they are ACRYLIC lacquer. If it says lacquer, my assumption is that it is a cellulose lacquer.
