Re: seam sealer?
 

I believe the factory used a sealer in the seam from the windshield down, but not on the rest of the cowl pieces on the outside. If I remember correctly the seams that were common to the inside of the cab were sealed on the inside.

I did the same.

The only thing that had seam-sealer on my truck was the roof gutter.
I scraped & replaced that, and seam-sealed everything else on the cab & doors with an epoxy sealer made by SEM. It comes in a twin tube set-up for a special caulk gun.
3M also makes a similar product.
If you search the early pages of my build, you will probably see it.

Re: seam sealer?
 

use the 2 part 3M seam sealer. You will have to buy the gun to dispense it. It's not too expensive. Get the heavy bodied seam sealer for all those areas. If the seam sealer is not two part it is junk.

Re: seam sealer?
 

Yes, two part seam sealer is much better in the long run. Even 3m one part tends to shrink and let water in and look crappy.

For most of that i used the no drip or thick or vertical seam sealer. I put it on with a brush on the wide flat areas, then, with thinner on a nitrile glove, wiped it out with my finger and smoothed it out. Any that you want to remove, easier to do before it dries!!! With paint on, you forget it's there. I also used the same stuff on the front hood seams (where the front panel connects) on the front fender seams (where body color changes to white if i recall.) and on the besides (the back vertical seams where the rear tail light panel connects.

It just really cleans up the seams, and if you make sure the seam is deep enough, looks stock but cleaner and keeps crap from getting stuck in those seams.
