I have been using the Walcom STM HVLP detail gun for several years now and highly recommend it. Mine has the standard 1.2 mm tip but I also have a 1.0 mm tip, and a 0.7 mm tip as well. You can really dial this gun down (or up) to spray paint accurately. The real advantage to this gun is that it is a gravity feed gun so you can mix up very small quantities of paint and spray. For example if you need just a drop or 2 of paint to touch something up, you can do it. Very economical on paint. You can find the gun, as well as many others at www.allsprayguns.com
