Well in the end I bit the bullet and went for it
Primer, colour and top coat all done,
All went ok except for the clear which ran in a few places, and in hind sight I could have spent another week on the prep as there's places that looked fine until the colour went on. The clear running was down to my total inexperience but learned a lot, the Liddles compressor wasn't chasing very much and coped well,
Just to wait for it to harden then I can start the interior fitting
