I'd skip the video's and just get the stuff and use it to learn, it's pretty simple if they have the basics of fiberglass resin down. Honestly to me you have to learn fabrication by doing it. Liquid Ice is just a clear casting resin. You work it pretty much the same as fiberglass resin, with one exception. Be very careful and slow when stirring the catalyst into it so you don't whip air into the mixture. Any air bubbles that you get in it will show up in the final part, and if you go too fast you'll cloud the whole mixture with 1000 tiny bubbles. Most of the "liquid ice" I've seen comes out of the can blue, then dries clear. They do have tints you can drop in it, but I've never used them. Really there aren't a lot of applications where the liquid is a better choice than just cutting and routering plexi the way you want it. The only real application is if you need some crazy shape that you just can't get with a router.
