I tried to use fender welting on my '47 panel. The product that I purchased was not wide enough to go past the fender mounting bolt holes. It looked like there was something between the fender and body originally, like roofing tar felt. I tried to tape the fender welt in place before installing the fender, it went on o.k. on a rear fender, but I couldn't get it in position on a front fender. I gave up at that point and cut some roofing tar paper as an anti-rattle gasket. I think if I were to use the fender welt, I'd want to figure out where it should be and glue it in place before installing the fender. I know it can look good, but I'm happy without.
