I don't like to use anything in my gun or on my needle, just so there's nothing that could affect auto work, and I don't miss it. Tip dry isn't an issue for me anymore, (once or twice an hour) but it used to be before I really got to know my paint. If it worked I would have snapped up something like this I think if it wasn't for the auto stuff. But would be good to know what the effect would be.
