One of my S12s has the dealers box that was all etched out, and I filled it in with weld but when I ground the weld all down I ended up with a few tiny small holes through out the box. My guess is the weld was not as tight as I thought or I ground out to much. I really do not want to weld it again It will be to much. Is there any other way to fill the small holes like a liquid steel or something?? I tried Loc tites version put when the heat from the heat gun hit it, it lifted right off (I was testing the filler before I baked the whole painted gun in the oven to see how it would hold up)
