i would say 400ml high build 2 coats 5 min warm time over each coat, smooth that with p600 wet, bit of degreaser, 1 litre 2040 super white, you can buy 400ml clear lacquer, if you can get a hold 2k paint that would be easier cause its already got the hardener in it and its easier to paint with than water based i would leave 5 min warm time for the lacquer coats aswell cause after the 1st coat if there is any imperfections you can usually get them out with 2000 grit thats if there is any. If you have to mix do the paint, hardener then thinner 300ml 200ml 100ml in the gun
