I have never understood this thinking. Why go through all the trouble, money, labor and time only to have your project rely on 40 something year old paint as the foundation? It makes absolutely no sense to me.
The extra money spent to strip off the old paint and start from scratch is a drop in the bucket in what you would spend if/when you need to redo the paint due to past problems.
If you get it blasted epoxy prime the entire thing right ASAP.
I would also ask any blasters how they strip paint. All the good ones I've talked too use a 2 step process, first plastic media to remove paint, then crushed glass for rust.
Epoxy is for adhesion and corrosion protection.
Urethane or high build primer has no adhesion or corrosion abilities but has high film build used to level out uneven surfaces.
You might want to rethink that HF gun, they are air hogs. Your compressor might have a hard time keeping them feed. Eastwoods has a gun or two that run at lower CFM levels as does Astro Pneumatic.
