My high school basketball coach used to ask: "Does practice make perfect?"
"Yes Sir" we would reply.
"No, perfect practice makes perfect!" he would correct us and make us run more lines. (Needless to say the man won the state championship, but we need beer and a camp fire for that story.)
...so I decided to practice on an extra fender I had laying around before shooting the roof. I've never used that type of primer mix nor that type of spray gun (or any for that matter) so if it pooped on anything I rather it wouldn't be my smooth as a baby's butt roof.
At first I could sum up the results in two dreaded words: ORANGE PEEL! So I decided to add 10% of the reducer to the mix, the guy at the paint store said I may need it, and heck I already paid for it so why not have it join the party, right? I also toyed with the gun, increasing and decreasing the amount of paint that comes out of it, I don't know which way I turned the knob, all I know there was no more orange peel.
Here are the pictures of my practice canvas, in it's original, prepped, and primered conditions:
