Why/How To Use Rivnuts In Your Van Build?

[@mcl925]

Out of all the van build videos I've watched, you are the first to show this drill adapter. After already having used the manual tool, I'll be purchasing the other one for the rest of my build.

If you drill a hole in your van do you seal it before putting a rivenut in? (Rust prevention?)
