Agree with
OG68 and

I sandblasted my own frame. This allows you to see if there are any cracks or even incomplete welds. I added a couple welds to my frame that I felt should have been there, but were short and incomplete welding.
I did my frame in 3 sections to make it more manageable. My frame only had surface rust and dirt and cleaned up well and didn't take a lot of time.
I used POR-15 as my base coat. I only used a single coat, not 2. Let it dry a good week or so. Then shot a top gloss coat of Rustoleum to seal it. Let that dry out as well.
I used Eastwood's internal frame coating with its extended hose to get up into all the enclosed frame areas. I used the zinc green. The stuff is real runny like water and will drip/spray out the frame holes and of course show up on a black painted frame. But not a problem on mine my intention was to put 1 final coat of black on the frame once I had it all completed.
