Were some, or all, of the black painted metal brackets, such as engine mounting brackets and muffler brackets dip painted by the factory? Some of mine appear to have been dip painted. This would have saved a lot of time at the factory. I may want to replicate the dip painting when restoring my bike. Has anyone tried the dip-painting method? Too sloppy and messy, or otherwise, vs. spray painting with the hobbyist rattle-can of paint?
