1970 Swinger 340 Hemi Orange 4 speed

Wow! Looks like you're already thru a lot of the rust repair. That'll be a nice Duster when you're done. Your rockers don't look as bad as mine were, so like you said in your thread, it might be better to just section in that back piece from a doner car. The rest of the rocker looks good from the inside down where those drains are? Mine wasn't thru where the inner was spot welded to the outer along that bottom seam, but it was paper thin in spots and would have rusted thru in no time. If yours is still good and showing little rust I'd pump some evaporust thru there for a few days and it'll make that pinch weld seam spotless.

Problem is finding a donor car to section that piece with. The Northeast is awful on cars. You cant find these cars around here anymore. The ones that are solid enough that these areas wouldnt be toast, are way to nice to cut up. My parts car is good for some pieces but not the rockers! I've been trying to find someone willing to sell me some from down south or out west, but no such luck.

As for the rest of the rockers, they are very solid. But I dont like the idea of putting an acid inside an area where i cant make sure its all the way clean again. I was planning on using Eastwood's Internal Frame Coating on these. It converts the rust, then seals it from further damage.
