Poor Design

Well a few day ago I spent the day cleaning my truck and decided to remove the door sills for better access of cleaning the carpet of built up dirt and grime. After removing the sills I noticed that there was water laying in the channel where the electrical wires run. I also noticed Crystallized salt build up from the winter. If you notice on the picture with the bottom of the truck sill exposed it shows yellow rubber like washer that must be used to stop the water from under the truck from coming in. Apparently they're NOT doing there job and allowing all this salt water from the winter to come in from under the truck and settle in the channel. Now I'm sure this is going to lead to all kinds of RUST to start forming so my idea I THINK is to maybe seal all the clips from the bottom of the truck with some kind of silicone.
What are your thoughts and suggestions on preventing this?


Yellow washers for sealing.

why did you have to tell me this

Better late then never, RIGHT.
Start cleaning.

LUBE the **** out of it before you re-install the covers.
Ford has been notorious for rotted door sills since the 70's. If you get it apart, put vaseline or some other thick petroleum based product on all hidden surfaces to prevent corrosion.
Alternatively, you could silicone the shit out of it - but then you'd never get them off again. It would prevent any moisture from getting through the holes. I have similar issues but am not planning to work on this stuff until the snow's melted and I can play outside again.

when does the snow melt?

Covers are back on, but they will be coming back off for some brain storming.
Last thing I want to see is RUST in there.

Hopefully ******* soon!
Calgary's weird - It hit 75 last January, but this January the average was below 3F. It can hit 90 in July, then snow the next weekend.
