Just got my bike a few weeks ago and plan the same thing. Going to start out with the speedo and ignition cover. Another member gave me these instructions the other day. So I cannot take credit (or blame).
"The plastidip is holding up pretty good. I haven't noticed any peeling so far.
To prepare the parts for plastidip, I just cleaned them to make sure there was no dirt or oil. Then I just sprayed the plastidip directly to the parts (no primer needed). I did about four coats on each part. I used about 1.5 cans since I messed up on speedometer cover on my first attempt.
I used this video for my spraying technique/time intervals :

I removed the parts from the bike so it would be easier to spray and not have to worry about over spray."
