Gun fluid tip

I notice in several places, there is warnings not to use 1.3MM fluid tips to only use 1.4

My main gun is a SATAJET RP Digital and I have never had any tip on it but a 1.3 I have shot PPG DCC and Clear with it for years and got great results. What would be the indications that I needed to step up to a 1.4 tip? Obviously, new nozzles sets are not cheap for a SATA gun, and being as old as it is, even finding a 1.4 for this gun is tough. The nozzle sets for this gun are discontinued long ago. This will be the first use of SPI material for me, and I want it to come out slick, but I sure don't want to spend the money if it is not absolutely necessary. Given the price of these nozzle sets, I may just buy an Iwata gun. What about all you guys? Anybody using a 1.3 to shoot the SPI single stage or universal clear. I really love this gun because of the built-in electronic pressure gauge in the handle. It sure makes setup a breeze.

the sata 1.3 is about like an iwata with a 1.4 . the sata is a hoser where the iwata is a slow and deliberate gun . you'll be fine John just do a few test runs .
good to see you here :)
Yea, PPG has finally priced me out of their product. You know I shoot a lot of red, and their red DCC's just keep getting more expensive by the day! I tried some SPI epoxy on my current project, (a 66 Nova), and I really liked it. Better than DP90 and way less expensive. I am still on the fence whether to use single stage or BC/CC. The PPG DCC is a great single stage, and it always yielded great results, but it is just getting too damn expensive!

When I think about it, I will send you some pics of the 56 Bel Air that I just finished, Red and white naturally! I have dropped off a bunch of the discussion boards I was on, as the conflicts and politics were just not to my liking. Sold the 67 Chevelle wagon with the 500 horse LS3 a couple of months ago, and am going to sell a couple of the Corvettes this spring. It is time to thin the herd a little and make some room in the shop, so I can build some more projects!
i'm hoping to start on the fleetline this spring but have to wait for the next ct scan in march before making any decisions . i have a c2 that a guy wants me to do but i don't think he and i would get along on a full build . i love doing corvettes but dont like being told how to do it .
i love barry's red in SS . not sure what color i want the fleetline yet . leaning towards a silver i use to do in the 70's .
