We obviously know that the reason that water can get in to the inside of the panels is those series of holes on the back part of the supports. In efforts to remove a path for water to traverse into the panel, what are the easy ways to fill those holes so the main threat is removed.


I don't know if this is a blessing or a curse, but I just moved out of Mom and Dad's house and with that came the time that I no longer have access to all of his welding equipment. Otherwise, welding some sheet stock to cover those holes seems logical to block that path of water entrance.


I was walking around Home Depot for unrelated projects and saw they had a special on spray expandable foam insulation. In lieu of the aforementioned sheetmetal replacement, what are your thoughts on filling the cavity with this foam to prevent the flow of water into the area? Would it keep the water out? The low weight addition would have literally no added weight, it is cheap (two cans was $7), and anybody could install it.


Where is the catch to the golden ticket?

I filled mine with it and so far so good...no rust or water ingress.

But get the weatherproof kind that repels water.

Done! Painted, rubbed, buffed and waxed (after 3 weeks) Good for my tastes.. It's a 14 year old truck...

Now I have to fix the passenger side door, it is rusting at the lower edge. I'm going to try some rust removal, then POR-15. I also have two other spots to repair on the passenger side, one under the clamshell door, and one under the bed, which will mean one patch and one sand and repaint.
Rust never sleeps......

Good Job! Your truck has made you a body man now lol.

How did the blending in go ? Looks good in the pics. I guess that would be my only concern with that particular repair...well in that area anyway. That said, Oxford White has to be one of the easiest to blend in tho lol.

Looks Great Man!

chinaclipper

Thanks!
The blending wasn't perfect, tho as you mentioned Oxford White is better then most colors.. You can see in the rear corner where I will have to remove some overspray... Oh well....
It worked for me tho. I am pleased..

Desert trucks, you got to love them....

Lol, I was just looking at welders today. My problem? I have very little rust except some surface rust in the rear bed chasis. I so want to learn to do bodywork.

Great job on the rockers!

chinaclipper

I know this thread is over 4 years old, but it is STILL the best thread I have ever seen for fixing those darn F-150 Ford truck rockers. I hope others have had a chance to "give it a try" like I did over 4 years ago.
Now I have to clean up some passenger side doors, and maybe even some work on the bed, but those rockers I fixed 4 years ago are STILL GOING STRONG! Now get up and do it !

Jbrew

That's great to hear chinaclipper, how are those rust spots at the welds doing at this point. That would of been a concern for me, as they could get bad fast. I think I asked you before and they were doing okay...how about now, still alright?

I still have a link handy from a guy who fixed the door bottoms on his rig if you it would help you. You most likley have it. If not, here it is, -

Very informative thread. I am doing some fixing up on my relatively new to me 2003 screw. Rockers and cab corners have the termites working. I don't think I want to tackle it myself from a time/energy/tools perspective ... prob start looking for someone to do it for me.
