Well, here's the problem... I don't care about making money on them. They are time consuming, though, and I'm pretty anal about results. Perhaps if we could get 2 or 3 folks with the same color at the same time, it'd be less of a bitch. And the parts are cheap. 2 nozzles is about $14. The primer, paint, and clear is about $20. I'll do masking tape for free. Shipping and packing materials, about $7, So it really wouldn't be much.
I've done the cargo floor and hood so far, just as other things in those areas have come up. Both have been a great difference for an already quiet vehicle. I have 2.5 more bulk packs in the garage for when I get time to do it all.
