What size tip is it? A lot of inexpensive HVLP guns have large tips because they usually wind up doing primer duty. I believe a 1.2mm or some such is a good choice for top coats where a 1.8mm is good for high fill primer. I have no trouble shooting top coat with a 1.0 tip on my el-cheapo detail gun.
My numbers may not be precise, my guns are hanging in the garage.
