You did a pretty nice and unique paint job Freeze, you should be proud !
Good break down on the methods and explanation also for curious first timers.
The last body I painted I tried the liquid mask for the first time. I applied 3 even coats via a soft 1/2" brush and used a old hair dryer between coats. Worked very well, I will be using the LM from now on for painting anything with more than 2 colors. Doing a simple 2 tone I'll be sticking with tape.
Finn, your spot on describing the usage of a exacto for cutting the lines and designs. I tried several methods and after experimenting I ultimately used the technique you stated and it worked best. I was able to cut smoother, rounder lines.
