Well, time to do some minimal filling here and there on e30 in a prep for the paint. Had a few dents straightened out and need to fill them smooth. Didn't know if I should epoxy prime the repair area first and than apply the filler or fill the bare metal.
I'm using premium filler that is good for the bare metal, galvanized, aluminum etc - Evercoat Rage Gold. There are a lot of info/debate on the web for this subject, mixed opinions. So I decided to experiment and see for myself. prepped the metal with 80 grit, cleaned well with ppg 330 and used 2K epoxy can on the part of the sanded area and left some of it bare. Applied the filler, let it cure and beat the crap out of it with the hammer, folded the sheet in half etc
Here is what I found: Looks like the filler actually chemically bonded to the epoxy primer and was harder to remove from the metal vs the filler applied directly to the bare metal. Figured I'd share. Those 2k epoxy primer cans are great for spot priming as well. Once mixed, can stays good up to a week...just clean the nozzle after the use.
The picture. The chipped area on the left side was not coated with primer, the filler came of clean when the metal was stretched. Middle chipped area still has epoxy/filler mess and was harder to scrape off
Punishment as it looks from the other side
