Yeah I think I misunderstood, I was thinking that phosphoric acid was the rust converter and had it in my mind that a rust inhibitor was more along the lines of a POR15 style product. My mistake haha.

Should I be worried about play sand being too aggressive and warping the metal? I was looking at alternative blast media and got overwhelmed...aluminum oxide was what I was looking at but it seemed like it may not be aggressive enough.

Thanks for the advice though, Ill be ready to start this project pretty soon hopefully! Although if it cools off too much I may have to delay til the spring.

I thought the same thing about the sand at first, but not really because you just touching up spots. You could go with other media, but sometimes they can get expensive. You could try baking soda first just to gently take the paint off around rust area and then only concentrate your more aggressive media on the actual rust.
