Most projects look better without fingerprints, and some projects even work better without them. The solar oven I’m thinking of building takes in solar energy through clear glass or plastic panels — and I don’t want to break out the glass cleaner to wipe off my fingerprints every time I use it. Film Buster claims to not only clean surfaces of dirt and fingerprints, but also to leave a protective coating that allows fingerprints to be wiped off with a soft cloth.
The marketing train derails — they mention that Film Buster could just possibly save your life by keeping your car windows clean! — but I still plan to pick up a quart bottle for $7.
