Alright! So tonight I want to tackle some frame rust. Its only surface rust, as pictured previously. Based on my reading on here, I should be hitting them with sandpaper (320-400 grit) than spraying with Rust Reformer. Tomorrow I will spray the whole frame with High Heat Ultra. Nearly all of the surface rust is far enough away from the firebox that I don't think heat will be a factor for the Rust Reformer, but can I use it on the area around the firebox bolt?
I wouldn't. That area is very heat sensitive which is part of the reason it tends to rust out so bad. I would hit that area with high heat primer after you remove the rust.
I see that some people only use the high-heat paint on the firebox and the frame that touches it. Should I just spray with the rest of the frame with non-high-heat of the same color? Saves a few bucks I suppose. Something like this would match the color and be half the price, but I dont really know how much of the frame should be sprayed with high heat. (

That is what I do. I spray the area around the cook box with Rusto High Heat Ultra Semi gloss and the rest of the frame with Rusto Gloss 2x. The 2X goes on much easier and looks better overall IMO. There is a small difference in sheen between the two, but they blend together well so that it is not really evident at all.
