What is the purpose of the sealer in the drip rails?

I imagine it's to prevent any water from resting directly on the metal surface area.....
But!!!
I have never noticed water resting up there to begin with...
Sooooo.......
I could be wrong!!!!!!!!

I used the SEM self leveling sealer in mine. It is a 2 part system that mixes as you squeeze it out. This does require a special caulking gun, but they aren't very expensive. It worked out great. I would recommend to tape the cab where you don't want the sealer to go and then pull the tape immediately after you install the sealer so that it can relevel if it goes over the tape. It sets up pretty quick. Also tape the end of the driprails by the door or it will run out all over the cab.
You will also need to get all or most of the old sealer out.
I think that I have seen this on e-bay with the gun.

there is a seam or overlap where the roof meets the drip rail that needs to be sealed. I suppose thats the reason for it.

Ohhhh!!!!

There is a seam that joins two peices of metal.So when you remove the drip rails like on a custom the seam has to be welded.Saw that in a magazine article.FWIW

If you have broken seam sealer there your cab will leak. If you have cab leaks, I would do a hkurry up sylicone seal over it. I now try and do this to every truck I bring in.

Ahh I see said the blind man.

Makes sense to have sealer there now.

Never bothered to remove it in any old truck I have had but always wondered way it was there.

Just noticed something interesting between my 2 '65s, the drip rails at the front of the cab are different widths.

My Custom Cab is about 7/8 of an inch wide

While the regular cab is about 1/2 an inch wide.

Is there a reason for the difference, build location maybe or maybe the CC is wider to protect the chrome?
