One small piece of advice is lighting.

I had eight double fluorescent fixtures in the garage ceiling at my last shop.
Painted the 32 there.

What helped was making up four double 4' fluorescent fixtures with 120V plugs.
These were placed on the floor pointed up at a 30 degree angle.

Two per side and they really helped light things up in the bottom area of the body.

Black paint so I needed all the help I could get....
