Been watching some full size auto painters and I want to try something with candy Black, I'm just struggling to find any, might be looking in the wrong places so thought I'd ask the experts.
Createx has a Candy2o in black, you just have to mix it with a binder -like UVLS 4050 gloss, or the like. There may be some that are solvent based, but being outside the US, I hesitate to even suggest anything due to potential shipping restrictions.
Over solvents should be ok. I have heard of people running into problems sandwiching water based between solvent, but I do not know much about it. I have often used a solvent aerosol for a base, water base for artwork and then clear with solvent without any problem though.
Maybe check out Inspire Airbrush paint. They do a range of solvent candy and might do a black.
