A thing of beauty mateYes totally agree, I don't normally drop coat on gloss, but as a rule I don't use 2K metallic as you can imagine trying to do a full flat side of a sprinter van with 2K metallic and not get a tiger strip effect is a bit of a pain,so had to do some sort of drop coat to blend it in, what an absolute pain in the **** tho!!
as an example I painted this with the same gun and the same brand of paint and got no dry lines or dark and light patches but as soon as its 2K metallic ahhhh it a nightmare.
