Here's another product to look at if you don't want to paint your frame and cover up its original look. I know that when I look at a car and its frame has been sprayed or painted with something like POR 15 or Rustoleum, I shy away from it. The product can be viewed and bought at www.keeprustaway.com. It is available in spray cans for about $10, but most of my experience with it has been with my trucks. I have them sprayed at their shop. I've been so pleased with the product that last year I bought a couple of spray cans and used them on the suspension and frame of my Corvette. Just throwing it out there. It's easier for me if you read about it rather than me writing about it.

I used it last year. As others have mentioned, it works great and is super easy to use, it's expensive and so is the shipping. There is both a black and a green and unfortunately after starting with the black and running out, I bought a can of the green by accident and my OCD does not like that part of the inside of the frame is black and part is green, but I have so many bigger issues to worry about now.
DEFINITELY keep some cardboard under the car when you spray as, like other's have already said the stuff is HARD to get off, even on my shiny epoxy garage floor, I've still got a spot or two of the stuff on the floor.
Like all rust converter products, AFAIK, do NOT apply it to clean, bare metal or you'll cause "instarust". That's probably my biggest regret / mistake on my engine bay frame rust removal / painting project. Went to all this effort to get to bare metal and then used a Rust Converter product in some areas to then have little bits of rust come through anyway.
