The blue spray gun that he sells i have already and is a great tool.

No - i wouldnt CC with it though.. good for cabinet resprays.

For CC on a PF i use a large nozzle airbrush ( 0.5mm) or a fine nozzle touch up spray gun.... main problem with nearly all CC's ive seen is the use of a standard spray gun and too heavy a coat... im not a fan of the thick CC.

The airbrush i by far my preferred method, it gives me total control... heavier where necessary and lighter in others... bumper areas etc get a bit more.

A spray gun will spray wide enough to cover a PF in 2 or 3 sweeps and so same amount of CC is applied everywhere.

The airbrushes on that site look good, but nozzle at 0.3mm is too small.. you need 0.5mm to enable large flow when wanted, but can move needle right up to restrict also
