the best thing that will help you is experience…you need to know what the paint looks like while spraying to know if you have enough paint for it to flow out smoothly. nothing you’ll learn here.
some key steps i take.
1.) get your spray pattern adjusted propperly (depends on what you’re spraying) small parts are better to use a tighter spray pattern or if you’re working on something larger and need to spray into tighter areas…adjust the gun for the tighter areas.
Spraying larger panels, you’ll generally use a broader spray pattern. Again, getting the settings correct is best taught through experience.
2.) Assuming your’re using the correct ratio’s and the correct reducer (medium reducer is a good all-around reducer,…but if it is exceptionaly warm out you’ll need a slower reducer) make sure you have your air pressure adjusted propperly to get full atomization of the paint.
to do this…spray something like a newspaper in light spurts. examine the spray to see that you don’t have clumps of paint, splatter, or ‘stringy’ looking paint.
any of these problems can stem from a dirty gun, too little/much air pressure, impropper mixed ratio of reducer/paint
3.) when spraying stay about 10-12 inches from the work piece through the entire spray. keep your spray distance with the contour of the work piece. This gives you a nice even coat and reduces the chances of runs or orange peel
4.) when spraying… start and stop off the work piece. Never start spraying while on the workpiece because the gun tends to splatter and if you aren’t moving fast enough when you start…you’ll get a nice run/drip.
5.) Clean your gun. A clean gun is a happy gun. (insert penis for gun and it makes sense too)
6.) I can’t think of anymore off-hand… so lastly, … pay me to teach you.
I’m not a master painter by any means, but these are the steps i have taken for successful sprays. Prep is 85% of a good paint job.
