I used 3M 1080 series vinyl. Not sure what the thickness is, but it's one of the higher quality wrap vinyls. Quality is really important, as it makes all the difference in how well the stuff goes down, getting air out etc. You can basically take this stuff, stick one edge down, then yank and stretch on it, crumple it into a ball, stick it to itself, then hit it with a heat gun and get it back perfect again.
Tools are pretty simple. Squeegee with a felt edge, break off style razor knife, microfiber towel or soft glove, and a good heat gun preferably with adjustable temp settings.
I basically learned how to do it by watching YouTube videos. 3M and Hexis both have great channels with lots of tutorials. If you wanna do the Scout let me know and I'll give you a hand.
