Seal truck bed

Anyone have a good way to seal those two slots at front of truck bed? Thanks!

 

You mean the drain holes?

 

No, the two slots up on the top rail.

 

Pictures?

 

I used foam blocks that came with my cover. Any areas I saw light I added Coax Seal to. Haven't had any leaks.

 

When I got my Leer cap on my last truck they just used silicone. Worked great. You can get it in black at any home improvement store.

 

Are you referring to the rubber plugs 62541-04010 and 62542-04010?

My Undercover came with a pair of "peel & stick" foam pads. They would be easy to make from materials at a hardware store. (You do need to remove the top rail to do it though. Just 5 torx screws.)

 

This is what I did, had to go back 3 times but think I finally got it. 3rd time I went out at night and held a flashlight on one side and looked from the other, that made it easy to find where the final leak(s) were.
