Need advice installing stepside fenders - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**dave6672** · 05-14-2018, 07:02 AM

I posted this in the paint and body section and got a couple of good responses, but thought I might get a few more here.........Soon I will be putting my newly painted step side fenders onto my newly painted bed sides. Question - what should I put, if anything, between the fenders and the bed where the fenders mount? I'm talking about the flange that is around the perimeter of the fenders where they make contact with the bed. Some type of seal or gasket? Seam sealer? Or just mount them up as is? Thanks!

Originally they were bolted on without anything between. The assembly manual says that there is a bead of sealer on the inside lip after assembly. I've seen some guys put a seal or welting between them.

I offer the same info. Basically, they are only virgin once...you repaint. Once installed that's it. I've seen a lot of trucks get the welting added, but not sure what help that does if any. It's really like any other two pieces of body bolted together.
