I just noticed rust on the bottom of my driver’s side front door. The rust is on the back of the door where the door skin is crimped to the door frame and has reached the bottom edge of the door. There is no rust on the other doors. The Blazer had been in an accident before I bought it. The door had been repainted at the time.
I’m planning on removing the rust and applying POR15 ( http://www.por15.com/POR-15/productinfo/1GB/ ) on the bare metal. If there is damage on the outside of the door, I’ll touch it up with a rattle can. I used POR 15 a few years back on the battery tray and was satisfied with the results. I’m more interested in stopping/slowing down the rust than making the door perfect.
If anybody has any suggestions, I would appreciate hearing them. I have to mail order the POR 15 so if there are any substitutes I would like to know.
