I have the Eastwood stuff and bought their paint encapsulate. I am using a Dremel on the rust areas to peal off the loose rust and then going to use that rust dissolver then paint it with the encapsulate and finally with base coat. I don't have large areas to use the dissolver like you other guys. I have rust around the inner window frames. I am trying not to buy a door. I have not started yet as I am just finishing up with front door and rear floor courtesy lights.

Well, you guys were right. That stuff sucks.
