Remember that high-solid primers like high-build type 2k urethanes require a larger (1.7mm) tip and setup internally than a regular paint gun. 3-gun sets are available for as little as $100 that include a primer gun with the larger tip, a paint/clear gun, and a 1.0mm tipped touch-up gun. Cutting (wet sanding) and buffing make up for a lot of shortcomings in inexpensive HVLP guns. So determining which is more valuable, your money or your time, is a determining factor in choosing a paint gun. A cheaper gun will require more time spent cutting and buffing than a top-of-the-line gun that lays paint out more evenly, but at an added price of several hundred dollars. A budget gun can be had for under $30, whereas a SATA 3000 digital runs around $650. You decide which is more important. Most folks will spend a little more time cutting and buffing than spend the extra on the fancy gun. The difference can be spent on go-fast goodies!

Whatever it is, you can ask other car builders that have done their own paint work, or if you know a painter, ask them. Best of all is to consult with the paint salesperson when you go to buy paint. They are a wealth of information. Utilize them. That's what they are there for.

''TWO MAIN TYPES OF ALL AUTOMOTIVE PAINT COLORS''
+
−
 
+

'''''SOLID paint'''''
+
−
Solid colors are a little easier than metallic to paint. If you mess up and get a run in them, they can be fixed rather easily by color sanding and buffing.
+

+
−
'''''Metallic paint'''''
+
−
Spraying metallic is a little different then spraying a solid color, they will mottle (have blotches of dark and light areas) and tiger stripe if sprayed incorrectly. The key to spraying metallic paint is to move the "dry spot" around. For example, spray one coat one direction, then the next coat in the direction 90 degrees to the first coat. Overlapping the coats up to 75% is another key to good metallic finishes. Remember anytime that the paint moves the metallic does as well, so if they run you will get the metallic all in one spot. With metallic always use the suggested reducers and mix the entire batch to be sprayed at the same time. I recommend this ANYTIME you paint. DO NOT play mad scientist/chemist. FOLLOW the instructions to the letter. The engineers at the paint companies spend millions on R&D, so they are already sure of the results you will get by mixing the product any given way. You, however, as an amature, are not. Do not re-invent the wheel.
