Hey ROb, great to see you posting again. I built the box, bondo'd the holes and nit picked the sides till I couldn't see any imperfections. I went over each side several times with a florescent light shining across the surface. I don't own a paint booth but have a friend that does. He sprayed it for me.I believe it wa a Dupont base/clear coat. Not sure if they wet sanded, but I'm positive it was buffed several times.
