All, I am in the process of manufacturing my own bumper. Using 3/16" steel sheet, 220V Lincoln Mig with 75%/25% CO2/Argon. The welds I'm laying down are structurally sound with good penetration. However, on the welds that will be visible I am grinding them down to look pretty. Every here and there, there are little craters or voids in the welds. What, other than slapping more weld on that area can be used to fill those voids prior to prime/paint? I was thinking about using Bondo, but my guess is that there is a product that is out there specifically for this. I found one such product from 3M called Scotch-Weld, but you have to cure it at 250F and my wife will have kittens if I try to put this bumper in her oven. Any help would be appreciated.
