You think doing it with a brush is a ball ache you should try spraying one, I think I got more buff coloured etch primer and 2k gloss black over my arms than on the chassis.
I've had some great fun painting chassis one that sticks out in my mind was an Exo super trike chassis that I did a few years ago for Rayvolution cars. Silly bugger here walked in to it 10 mins after the final coat was put on a day before it was due to be at the Stafford show.
