The tint and UV coatings come in a bottle and can be applied? Can that be done at home?

It was concentrated liquid that was mixed with water and heated. If you can get your hands on it, yeah, it can be done at home.

Edit: We used BPI(?) dyes and UV. Make sure you don't have anything other than scratch coating. A/R, Mirror, etc. will likely craze in the heat.
