Filling a ding on a big block valve cover advice needed!

OK, here is how it is done. I do this all the time when I powdercoat valve covers, motorcycle fenders, atc. It also works on Stainless Steel Trim. This explanation could take a long time, but I will give you the short version. On the back side of that dent, you will see the where it bumps out. With the FRONT side od the dent properly supported against a HARD surface (preferably an anvil or something similar) gently tap on the back side of the dent with a hammer (ball peen works well). the idea is to stretch the metal back out slowly. If the FRONT side of the dent is not properly supported against something hard, you can easily wind up with a dent that now pops OUT. When it looks close, go to the front side of the dent to assess it. I use a felt tip marker like guide coat by marking on the dent and then blocking the area with 120 dry sandpaper on a hard rubber sanding block. Don't worry, you wont go through the metal. You will be able to see any low spots because there will still be some marker ink in them. then carefully determine where the BACK side of the low spot is, mark it with a small circle, carefully support the part of the front side where the low spot is on the hard surface and gently tap on the back side where you made the mark. repeat until the dent is gone. It's really easy.
