Rustprotection

I intend to improve (well, I don't know if this is the right word) the rustprotection in the chassis, forks and whatever it is called in english. I know I've seen drawings of where to drill holes in the chassis and how to “fill it” with rust protection. Do you have information about this or do you know where and how I can find it? I've tried to contact Valvoline and other "anti-rust companies" to get this information, so far without luck...

See "What's this?" for my e-post address.
