Thread: Chassis rust proofing D2

What's peoples advice?
Just hosed out about a bucket of sand from my d2 chassis rails...
What' a good option to rust-proof the inside of them and how'd ya do it? What's peoples recomendations for products? Especially if some rust is already present and can't be accessed other than by pressure cleaner.

ps I notice there is not enought drain holes at low points, and guess drilling any would compromise the chassis strength?
