I am a hobbyist who only gets to paint a couple times a year, I have 2 904he with both hvlp and lvlp air caps. one for primer one for base and clear, seeing I dont paint often I love the ease of use of these guns I can get high solids clear to lay like glass!
Warwick spray guns quality is VERY good and reasonably priced making them a great value.
The replacement parts are also VERY good quality. We have been using them for years in our repair shop with no problems. We at Paint Sprayers Unlimited would highly recommend using any of Warwick's products.
