Also, going back to the renegade for a second: I see a bunch of people
selling this thing. I have no idea what this thing is or where it is in the airbrush - when I've broken it down, as I have many many times, I have never seen this part. If this is what you are referring to, MoM - I don't know how to service it but it seems different than the part that is not user serviceable.
I wasn't sure if it was with the Renegades or if that was a feature they introduced with the Krome. I've never had the opportunity to take apart any of the Renegades, so I wasn't sure. If I mentioned it as more than a possibility, sorry about the confusion. And that ebay link is for a needle seal for a badger 350, so I don't know if that would have anything to do with a Renegade since the part pictured doesnt match anything in the parts diagram.
For your question about using the Sotar Needle stop, thats done pretty much by feel. Since most paints flow different, and will work different depending on PSI, humidity and even barometric pressure can affect it- those little metering marks on the needle stop aren't really all that helpful with acrylic paints. If you do use the needle stop, the easiest method is to just test spray and dial it in, and it then limits the maximum spray. Its rather helpful for getting consistency with freehand lines and other really small work. But as Scooty mentioned, alot of people dont even use it, so its a preference thing.
One thing I will mention on the SOTAR- as you mentioned PTFE seals on hte spray heads- the SOTAR does have one- and its a very very sneaky little piece of plastic- I call it the White Ninja- as it will pop off when you disassemble it for cleaning and do a really good job of trying to disappear. Dont let the happen or you'll have a huge backflow/bubbling issue. In the WGC facebook group we just had a user with this happen and they went through the whole trouble shooting list until I asked if that plastic ring was in place

Its pretty much the only Badger brush with that sort of a ring on it too...
Anyhow, hope you enjoy that SOTAR, its a good piece of gear
