Don't waste money, use simple white mylar or snow white paint. I am learning over time both deteriorate and will need to be replenished due to the lighting though.

+1 for what WashougalWonder said.

That stuff is meant for exterior use. It is going to off gas something terrible. If you want to get fancy get some Reflectix from Home Depot. It's 95% reflective, waterproof, it won't deteriorate, and you can install it in an hour.
