Maybe not a strip of BMF. One edge would have too straight look to it. Maybe taking some chrome paint a 10-0 brush and painting a very fine line between the "weld" and the surrouonding metal. if you leave a few brush marks (letting the color show) this would duplicate the "swirl" marks from using a disc grinder on the metal just prior to welding. I've done this painting style before and it looks good, but I haven't tried the "welding" bead like this! Any chance of a "how to" explination? I'd love to duplicate this on a few of the stock car models (I love NASCAR, but I try and build short track form where we race weekly).
