Important Rust/Screw Question..

[IdahoMan]

I've noticed on some of the screws that I have removed, such as the kick-panel and drip-rail screws, there is a hard amber-colored rubber/wax coating involved.

Being very rust-paranoid, I'd like to ask just what this coating is, where do get it, and how is it properly applied. I assume it is some kind of coating to help keep the threading of the socket from corrosion? A lot of these screws go straight through the body metal.

It would suck to go through a lot of hard work restoring something, only to have rust start growing right from a corner, hole or socket because it wasn't fastened or sealed right. What's the proper procedure for drilling/screwing??

Thank you.


Sincerely,
IdahoMan
