I'm not in the trade but worked in a mates bodyshop for a week while painting my Levin. I was basically just a prep monkey. I was thinking it might be something i'd like to do for a career change (currently a dental technician), bollocks to that. It's bloody hard work and prep is mind numbingly boring. Only reason I saw the week out was because it was my own car and I was saving a grand by doing it myself.
There is good money in it from what I saw, think it's fair to say it's well earnt. Can see why a paint job costs as much as it does.
