Next up is cleaning up the rockers. Structurally they are solid, but because this car used to run 930 rocker trims there are a bunch of screw holes in them. Most of them are not accessible from the backside, making welding them up more difficult (can’t get a copper pad behind them). Also I don’t want to cook the paint if I can avoid it. In looking at options I came across the idea of using solder to fill the holes and so I gave it a try. First couple attempts went well and I like the results.
I used a small flap disc to take off the paint and rust around the holes.
Then I smeared on a little flux and used my soldering iron to flow the solder into and across the holes.
Then I ground it back down flush with the flap disc.
Next up is finish filling the other holes, hit them with etching primer, and then blend with a touch of filler. I think I’ll then just hit the entirety of the lower rocker with epoxy bedliner to finish it off.
