Never heard of that mate ? What is it ?
A little bottle i have of rust converter! Paint it on, well, it's like water not paint. Anyway, apply it and it removes the rust! Its pretty good stuff. Only prob is, i did it once, took all the paint off the surrounding area, sanded it back etc... did the trustan, and it was all bare metal ready to paint, so i went to bed, and it was rusty again in the morning
