Hello,
I am new to the site and so far it seems very interesting. Great videos!
Here are my two questions.
I am going to attempt my first metallic base and clear paint job this week and I was wondering if there was anything I should know to aid in this adventure. I have been reading and watching videos and reading and watching and reading and watching for more than a month now. Mentally I feel ready.
Secondly, Whats the best way to tune in a gun for metallic? I have had issue sin the past with PSI at the gun inlet to the to spray tip. I run 45 to 55 PSI into the gun regulator, then dial in the air knob so that when I pull the trigger the gauge would show like a 15 psi drop. is this correct or wrong? The gun (HTD 6900 series) isnt the best but good for what I am doing. I just feel the material has been coming out to heavy in past jobs. They came out good. That is when I painted a couple last year (BC/CC). Some people actually thought it was done at a shop, but non the less it seemed a bit heavy.
The cars I am going to be painting is a friends 85 Monte Carlo SS and then secondly my 67 GTO convertible. I know, practice on the friends first, lol…
I would appreciate any information on these matters.
Thank you in advance.

Hi guy, I am not very experienced but I am going to try to help you. I do not know your gun but mine is a DeVilbiss Plus and this is what I do: First open the fluid tip all the way out (Counterclockwise) then press the trigger all the way and start turning the fluid knob clockwise until you feel pressure on the trigger, next you open the fan knob again counterclockwise all the way, next adjust the pressure on the inlet valve to the recommended pressure either by your gun manufacturer or the data sheet on the material to spray, next assuming you have your material ready and in the cup you press the trigger and trim the fan just enough to trim the edges of the fan, the final step you spray a test pattern on a sheet of paper and adjust your pressure a little at a time + or – until you get the results that is best for you. If someone cares enough to write and help you, follow their advise as mine is very limited, like I said I do not have the experience that the rest of the forum have. Good luck and welcome here
