I don't know about that product, sounds like a rust converter. Sounds like the one advertised on AgDay, which comes from the Rust Guy.
I think the question is...can u rely on the product doing what it's advertised to do....and then for how long.
I don't know the extent of ur rust, but if it was me and I didn't want to go full boat and blast, I would wire brush the the frame and paint with Rustoleum red primer, 2 coats, and then top coat it with 2 coats enamel.
Now I know that will go the distance because I did it to a frame back in the 70's and it's still on the frame looking decent except for a few rock chips.
Beyond that u can spend bigger bucks and use different products like Chassis Saver and Por15 which are supposed to be better, but I have yet to hear about any proof that it holds up any better 35 years later.
I guess we will have to wait a few years to prove the outcome and I imagine they will hold up just as well if not better, the only difference is the cost.
