Thanks very much! The hardest part is figuring out the right amount of liquid mask. A consistent way to add medium thick coats is via spray gun. I use a high-flow one from Harbor Freight. Obviously brushing on works just as good, but better to err on the side of more coats. I've spent hours laying out and cutting only to find that the mask was too thin and won't peel off. Maddening!
I am going to have to study up on the liquid mask. I never knew it existed, let alone use it. Do you apply the number of masking coats based on the number of different colors you will be using? I am going to be doing something VERY basic since it will be my first time. I guess worst case scenario, you could acetone the inside and start all over :/

The thicker you put it on the better it is to get it off. It's easy to use but a longer process in my opinion.
I'd agree that it's a longer process, but well worth it, as you get almost no paint bleed with liquid mask. With tape--even the best blue 3M fine line vinyl tape--you'll get some bleeding under the tape, especially around tight corners, nooks & crannies.

No you apply multiple coats of liquid mask, letting them dry in between. The mask should peel away easily. Then you use an x-axto to slice in to the mask being careful not to cut deeply in to the lexan. You cut the mask all at one time every where two edges of colors meet. Then you remove the mask only from the darkest paint first, and spray with light coats of paint. Then remove the next darkest color's mask and paint. Continue this way for all colors. Since you're painting on the inside it won't matter if you paint lighter colors over darker colors because they won't show through or alter the hue.
