1.3 / 1.4 tips for SPI clear
For SPI Universal 4000-1clear:
I've got a 1.3 tip for my color/clear gun. SPI says to use 1.4 tip.
I'm an old school nitro & enamel guy from the 70's and 80's and used to use just about anything to spritz a car, not much experience with the new stuff. Are they being overly cautious or is there really such a difference 'tween 1.3 and 1.4 tips?
