I use used sanding belts from work, bonded with wood glue, I paint it the cheap Wally world blue first, not entirely, just a quick coat, then primer gray and allow it to dry, then gloss and flat black dustings. Before the last paint cures, I wipe with a rag(non-lint) and thinner until it looks right. Practice Makes Perfect. After a complete curing, I mask off and spray the double yellows and/or white lines. I also make some great guard rail out of the cartons that 2 1/2 dozen eggs come with. And I beams from Index cards.
