I have a question about how to paint the door post and cowl with welting on a roadster/phaeton. You can see by the picture the front of the cowl post is painted the trim color. The cowl/gas tank and welting are painted the main body color. In what order is the painting done? Is the cowl post painted the trim color first, then the cowl and gas tank bolted in place and then somehow mask off the door post before painting the cowl/gas tank and cowl welting? I guess the cowl/gas tank could be painted separately, then installed, but then how would the welting be painted main body color?
