This a pic of the inside of the outer rocker. Looks like mild surface rust to me, but I'm looking for other opinions. I was thinking of wire wheeling it and then coating with Master Series Silver or epoxy. Good idea? What do you guys think?
When the rust leaves a depression in the metal itís no longer surface rust, thatís my opinion. Your best bet for the longest repair is to blast the rust out and epoxy prime. Nobody will ever convince me applying a coating over the top of rust works.
The side doesnít look too bad. The bottom looks like it may have some damage. I agree with Caper, if you can blast it, that would be best. If not, wire wheel, or whatever you can to get it clean. Treat it with Ospho, then epoxy prime, or use Master Series Silver.
Be careful when welding etc. The rockers were galvanized and can give off toxic fumes.

Look itís lasted for 50 years unprotected. Wire brushing and coating has to be better than nothing. You can blast and epoxy, sure. But, unprotected, paint on or sprayed, all will probably outlast you. If your prepping for your grandkids, you better epoxy. 😉

The bottom is actually pretty clean. No rust at all. The orange you see is from the reinforcement pans for the Convertible. They had some pretty serious rust almost welded to them from the floor pan where itís sandwiched between it and the inner rocker. Rust dust. Iíll post a few more pics.
Couldnít find any local. Ended up using Permatex rust treatment in a spray form that I had in the garage. Hope I didnít screw up. If I did I can always take it off I guess and use something else. Got 99% of the rust off then sprayed the Permatex on it. Turned the whole thing black. Figured Iíd top coat it with the Master Series silver.
Ospho/Phosphoric Acid or, if you can't find it, Naval Jelly. Wipe excess let dry, weld it back up then epoxy prime or Master Series Silver using a 360* spray wand through the drain holes. While still "semi-wet", open up the drain holes with a Q-Tip so they don't get painted over.
