Hey What's up fellow's, im new to the world of autobody repair and paint, i'm looking to get some knowledge and advice from your experience. i will be taking a evening college course in the fall , so i can work on my and my families vehicles. I'm also doing it to use as a hobby and maybe some money out of it? i purchased a sata jet rp2, off ebay and it appears to have a fitting on it.i have a sata gun cup that when i remove the fitting it fits directly on the gun. Just wondering if anybody can tell me what cups is the fitting used for? I also would like to ask, would it be better to use a 1.4 nozzle for base and coat, rather than a 1.3? that's what i have on the gun....thanks for any advice you can help me with, and look forward to gaining some knowledge from you guy's.. thanks peace...

That is an adapter for 3M PPS cups. Not sure what to tell you about the nozzle size. I have never used an older RP.

Thanks, i appreciate it, will look up the 3m pps cup system..peace..

Try the 1.3 first. It puts out plenty of paint.

Thanks, will do! peace"
