do yourself a big favor and drop some dough on a decent gun. It's a big help. I've had this one for a few years and literally call it ol trusty.

You also might wanna throw a thread up in Paint and Body. Lotta very knowledgeable kats in there.
Your gun should not drip from the tip. Check your needle slide, make sure tthe tip's traveling all the way back into the cap. Cleanliness is everything. If there a HF near you, go get the cheap gun cleaning kit they have, it helps a lot.
Nice lookin' truck, good luck!
