From what I read Ospho will work for what I want, when I'm ready to clean and paint the frame. Some have said that after the Ospho treatment if you strip it off the rust is still under it (but it's supposed to be, right?) and you still won't have a proper bond when you apply primer/paint. I'm kinda new to this.
Just fishing for some thoughts, feelings, opinions, suggestions, etc. Consequently the guys that didn't recommend Ospho also didn't like POR15 for the same reason, tantamount to taking cheap short cuts that will come back to bite you later.
What say you?

I've used a mild phosphoric acid rinse, like Ospho, after sandblasting to prevent flash rust before painting. The destructions say to rinse with water. I Let it dry completely. Then wipe it off with thinner just before painting or powder coat.
I wouldn't use it to "convert" rust for the same reason I wouldn't use POR15. Both may work... I think covering up the tumor just seems like a bad idea especially when you're actually trying to kill the cancer. Kinda like using face paint on a Carcinoma.
