- Next we focused on the bed rails and found that water was hitting the bottom of the bed rail trim from road spray. I asked Ford and was advised that most truck do not include the rear fender skirts that would help with this. Since the parts to complete this would be around $150 I chose the more economical route: expanding foam insulation spray from Home Depot.
- Lastly we found more holes at the front of the bed just under where hte canopy mates to the front bed rail. There is a small hole at either side of the bed front panel where in meets the side panel. Once again I used the expanding foam to plug the holes.
I will update all once I get some time on these fixes.
I read somewhere on here that certain chemicals in the expanding foam will attack the metal and cause it to rust/corrode. I think it was in regard to someone spraying it in the cab roof cavity and it caused it to eat away at it from the inside. I don't know how true this is, but I would definitely do some further research on it before spraying it somewhere that I couldn't keep a constant eye on it. Just a thought.
