I'm currently using Akzo Nobel 2-part epoxy interior primer on my RV-14A build. I've had a few priming sessions, but I'm still not entirely comfortable with using a chromate based primer. There are some water-based single component primers, but I understand they aren't as durable as epoxy primers and can be wiped off the certain solvents.
I recently discovered a chromate-free epoxy primer made by PPG Aerospace. It seems to be just what I'm looking for, but it's pricey ($327/gal on SkyGeek) compared to $189/gal for the Akzo Nobel stuff.
Has anybody had any experience with this primer? I'm mostly interested in its durability compared to the chromate-based stuff. I'm willing to pay the extra money if the associated cancer risk can be significantly reduced or eliminated.
