I have been doing this a long time and tried most all the new and latest stuff and I keep going back to Rustoleum. It's the absolute best product, IMO. And no, you don't have to get all the rust off. You do however need to get all the loose rust and scale off. I hear everybody hollering "POR15" all the time. I've used it. It's a GIANT MESS. It will get up your butt and there's no explanation of how it got there. It gets everywhere. Plus, you have the extra expense and labor of having to top coat it, because ultra violet light breaks it down? Paint the **** TWICE? I don't think so, Tim. Not this honky. One time and done. Rustoleum.
