I just watched the LiquaMask video from Laserbits website. (BTW, if anyone from Laserbits is reading this, scrub the audio. File is too large and streams very choppy as a result. Audio is a non essential part here anyway, not to mention we can all use less elevator music in our lives Otherwise great video!)

questions #1:
Has anyone used this product masking unsealed wood? Video shows it being used on sealed wood, which frankly is totally unnecessary. The finish does that anyway....

question #2:
Can this be used to mask already etched areas (on stone, acrylic, glass, wood etc) in MULTI COLOR applications, to protect certain areas from receiving certain colors. For example, would it be possible to etch the entire design onto a substrate, then carefully brush on LiquaMask to cover portions where I do NOT want color1 to go. Apply color1. Then peel off Liquamask, and apply over already color filled color1 and apply color2 where AquaMask has been peeled from. Can this be done?

Thanks!
