Far from a professional. I just use a HPLV gun (got a little 4oz job from Harbor Freight). I turn down my compressor to 60psi and hold the gun to 25psi. If you go to the website they give you the basics on how to spray their coatings. I had the headers blasted and then just wiped them down with mineral spirits and let dry then sprayed the coating. Intake I just pressure washed and cleaned really well then sprayed. Bearings I hit with a scothbrite pad then cleaned with alcohol then sprayed. You can buy their tester bottles and it will go a long way. The bearings and piston skirts I used about 6 oz of coating and around 2 oz on the piston tops and cc. I bought a pint of the titanium color for the intake and headers and I still have half a bottle.
Also do several test passes until you get the pattern you want down. I usually hit the entire part with a light coat then wait a few minutes and start hitting the hard to reach spots and then go from there. Mostly like painting a car or anything else with a HPLV spray gun.
