Some paint questions for the guys who know paint

I'm using the orange cap too for base. The silver cap for clear. The urethane wave that I've been getting is very very slight when I nail it good. Blocks out really easy but wish I could skip this step.

Do you guys add any reducer? 5-10% to get it to flow out more. Doubt it would help much I bet it's more a matter of technique, gun setup, equipment and environment.
Wish I had better technique but teaching myself makes it hard. Just glad I have good tools which has been the differnece maker for me. I'm using a SPI clear which is a very high solids clear. I love spraying it.

I bet you'll like the Iwata the more you use it for clear. I hear the RP is a hoser. The wave is more of a material thickness problem from what I read.
I'm not that fast to use the Sata.

Redness and Rob: Which tip do you use for your Iwata for clear?

Here's a pretty good read when I found a while back
