You can make clear coat look better easier but original is single stage. And single stage is easier to repair problems. I use PPG Concept acrylic urethane. Wheel wells are painted body color. Undercarriage and belly pans are painted grey primer. I would just use a good quality grey paint acrylic urethane. Don't undercoat unless it is already undercoated. In which case it is almost impossible to remove the old undercoat. --- On Wed, 8/19/09, James Dwan <james_dwan_2000@xxxxxxxxx> wrote: From: James Dwan <james_dwan_2000@xxxxxxxxx> Subject: [tcb] Question about painting my 23 Window To: tcb@xxxxxxxxxxxxx Date: Wednesday, August 19, 2009, 9:05 AM The Bus has been blasted and body work is in progress. I am trying to decide if I should go single stage or clear coat. What are the pros and cons? Also, Jay, is suggesting that I use an undercoat for the wheel wells, splash pans and belly pans. My concern is that if anything like a rock hits the Bus with clear coat on it, it would be more difficult to touch it up than if it were single stage. Also the undercoating, even if mixed with paint wouldn't even resemble stock. I plan on driving it around the lake and to all the shows but not too much more than that. And lastly, should I paint the wheel wells and belly pans black? Or were they red? I am searching The Samba for pics but it's slow going. Thanks!
