i am an amatuer hobby painter doing maybe one or two paint jobs a year on antique gass engines or motorscooters. i have been using a binks #7 for about 25 years. it is getting as little tired and i understand the newer self etching primers and paints work better with a gavity feed gun. there is such a variety of these guns from under $100 to over $500 some hvlp some not. some have one nozzle some have several. i know it is not best but i use one gun for primer as well as paint. i don’t want a cheap gun that wont give good results and cain’t see spending a fortune on more gun than i need. as a hobbiest funds are limited so i want to get as much as i can for my money.any suggestions will be appreciated.
