You need an IT guy from PPG to set that up for you. If you own your own store you should know that.
Another thing to keep in mind is never put a digital spray gun or any gauge in a gun cleaner.
I got everything from Amazon.
The only thing I didn’t like about that one is that you would need to bring electricity in the booth. Also the battery for the 3M Sungun can be rebuilt for a lot less than buying a new one.
You have the software version that is not free. You would need to call PPG to get the codes but they will not give them to you unless you are a registered user.
Go easy on your first coat of single stage.
You won’t be disappointed in gloss. Do go back to back as stated in the data sheets.
If the paint is in decent shape sand with 180-220.
It can absolutely be done. Not with waterbase though. If your spraying mettalic base make sure the clear is set up enough before you re-clear or the base will move.
