I have a 66 Suburban I am restoring, and I'm getting to the point of working on the interior. The burb still has the original cardboard type material in the ceiling, and has the original paint on it. My questions are: How well will that ceiling material repaint, and also, will a HVLP Gun, with the top cup on it, work for painting the ceiling. I am not a body man, and the gun is just a harbor freight toy. It has worked extremely well on the engine compartment and wheels. Thanks for your help.
