NOT A PAINTER

I have been using the same products for many years. I am used to them, and they work very well for me. That being said, I am going to try some of this CRE primer. I am helping a friend with a 56 Studebaker Power Hawk. I painted it a while back, and it is all color sanded and polished now. He has a 67 Camaro we will be doing next. I will try some on that. Is it DTM? I strip down to bare metal and then use a DTM epoxy. Is that what you do with the CRE?
I'm sure you see it to a lesser extent, but out here in California every time you learn to like/trust a product it gets outlawed... I have paints and primers I bought five years ago that the reducer/activator/catalyst can't be sourced anymore... I've brought products back while on business trips..

At times I've mixed products that aren't supposed to be used together just to see what happens.. With the current materials cost I hate to throw away product...

Not gonna try that on a full paint job to much work to strip it I things go poorly, but painting small parts I'll risk it..
