Checking back in on this thread it occurred to me some people might think screwing welting strips long enough for their parts to plywood and painting them like I did the test samples would be a good way to paint them. It is NOT a good way because the paint will bridge between the welting and wood. I didn't care for my paint tests but you don't want to spray pieces you'll be using that way because you'll get crappy edges. Best to mount them on the edge of something like they will be when installed to get good paint coverage and edges. Then make sure the paint doesn't bridge the edge and dry. I'm going to try and make some fixtures to hold the welting so both edges can be painted without bridging. If they work out I'll post in this thread. Meanwhile here's a couple pics of how to keep the welting from being glued down by the paint bridging.
