So much of it depends on how bad your frame is in regards to rust...and how much time you want to put into it. And what oyu expect whentiu us doen adnIF oyu care if it rusts right back in few years due to not being done correctly.
It can be sent off and be acid dipped and primed.
POR-15 is an excellent product to use as long as you use the products as they recommend so it adheres to the frame.
Some people will wipe off the metal and shoot something on it adn call it done ...while others will sand blast the frame and powder coat it...and some will use wire wheels and grinding discs...and on and on and on.
So many different options...i am sure you will get your fair share of ideas.
Working on a 1972 convertible frame off restoration.
Any suggestions on what paint to use on the frame?
It depends on what your goals are. If you want it to look like a show car - better than it originally came off the line - have it sand blasted and powder coated. If you are looking for durable protection, use POR 15 as directed.
I had my frame dipped to remove rust, neutralized, it, strengthened the welds on the lower A arm mounts where they tend to crack, went over everything with wire brushes & an angle grinder, and coated with POR 15. I also covered the holes in the frame with tape (section by section), poured in cans of POR 15 and heaved the frame around the yard to coat the inside of the frame (Several cars stopped to watch the crazy man wrestle a car frame.) and then drained the paint from the frame.
I live in Florida near the Gulf (EVERYTHING RUSTS!!) and after more than 10 years, the frame is still rust free.

My 71 convertible frame was in not too bad shape, some pitting. I blasted (crushed glass) in my driveway under a tarp. I am working with a limited budget but also want good results. Lots of research on various auto forums and this is what I did....
Primer with a black Transtar 2K primer, then used Rustoleum Professional (1 quart semi gloss to 1.5 quart of flat) cut with Acetone and a hardener compatible with the Rustoleum enamel. 8:4:1. I spray it through a cheap HVLP gun with a 1.8 mm tip. I know this car will not be driven in sand and salt conditions, and maybe a couple thousand miles a year. The finish will outlast me.
