I have seen it her before but cannot find the thread. Looking for a liquid to apply to rust that stops it and I can then paint over it. Por15 is black and what I used before was clear. I am stumped. Thanks all
I believe por-15 makes a clear version of the black stuff, although harder to find. Rustoleum makes a thinner liquid (light blue but almost clear) called "Krud Cutter" .... works pretty well and a lot cheaper than por-15...
