Good luck with that.
When you spray gel it has the texture of a styrofoam cup. It took 3 guys a week to sand and buff the gel. Also they tape all the strips in first, then spray the base color. Pull the taped stripes, then mask off the base color and shoot in the strips. This way they can sand all the colors at the same time and its all flush.
If I was going to Macco I would have them shot what they know ... paint.
