Anyway, I have been told that the POR 15 is an awesome product when used according to the directions. That's why I asked if he was going to use it on this truck. He's doing a lot of work to make it really nice, and as much surface rust as it has I sure don't want to see him have any problems come back later since it's going to be such a sweet ride when he's done.
I have bought some POR 15 for my truck, and hadn't heard about this other chemical. I need to do a little bit of research on it and see how it works before I try to use the POR 15 that I have on my truck. Thanks for the heads up on the other chemical. ...Joe

THey have 3 steps, check their site.
Step 1 = Marine clean.. Its basically a degreaser to get oil and junk off.
Step 2 = Metal ready.. Thats what changes the composition of the rust.
Step 3 = Por 15.
I like it so far, i just dont like the part of spraying it with water. Most people have their truck apart in their garage.. Not like they can move it outside to wash parts of their bare metal down with water ya know.
