Peelable mask coating

So while playing around on YouTube, I stumbled upon an interesting product that is touted for laser marking but looks like it could be useful for masking when doing cnc work. A site called laserbits has a product called liquamask http://www.laserbits.com/laser-supplies/liquamask.html it is a bit pricey but looks like it would last awhile. Searching for more info, I came across the owners post on a wood working forum and he had this to say;
“The down side to the LiquaMask is the drying time and that it is not recommended for bare, uncoated wood. Customers have reported major reductions in drying time by using a fan, not heat, to dry the liquid coating. As for bare uncoated wood, there is not a great solution for that right now but our team has been working a special formulation for this application.” http://www.sawmillcreek.org/showthread.php?164472-LiquaMask

The same thread was comparing liquamask to this product which is cheaper. http://generalchemicalcorp.mybigcommerce.com/categories/Peelable-Coatings%2C-Strippable-Coatings%2C-Maskants/Laser-Protection-Masking/

Anyway I thought I would share the find and see if anyone has used it or thinks it is something better than tape masking.
