[QUOTE="thill, post: 506974, member: 4972"] I have had outstanding success with both gray Marine Tex and JB Weld. The trick is to wipe down with Acetone or spray with carb cleaner to remove any oil film, and then wire-brush immediately before repair. Then use a hair dryer or heat gun to warm the repair area immediately after application. Warming it up thins the epoxy a little, and helps give a more secure bond into the "toothed" areas caused by the wire-brushing. Do a small area at a time, focusing on getting the metal really clean. I've never had either one fail when prepped properly. They are permanent fixes for pitting like you show. Once dry, you can sand, prime and paint as desired. If the spots are blown all the way through and are really big, there are other things to consider, but these will work for those, too. I might add a metal patch, if bigger than 1/4" hole. [/QUOTE]
