I did my black-out on the car after Bob confirmed all are and a basic walk-through on how to get it done. I didn't use flat black. I used a semi-gloss. Everything sticks to flat paint.
99.9% of us are NOT thinking of Concours. We're practical. We drive them and you'll note in southern states they scoop anything that flies right out of the air. I can wipe them out easily and they look so much better blacked out.
I also didn't want ANY sealer oozing out, so I explained in the other thread how I did mine. No ooze and noting all over the blue paint.
Anyway, I will go take a couple of pictures and modify my post with added pictures.
