They make a gray colored stuff that goes on real heavy. I don't know what it is or called.

When I took my RV back to the manufacturer in Middlebury Ind, near Elkhart, they asked if I ever resealed to the roof. I said no and it wasn't leaking. They said it was standard practice to reseal the seams from time to time. When I got it back there was a fresh coat of something thick and gray on all the roof seams.

That's all I got, the seams do move a little when the trailer is going down the road, so I'm guessing something flexiable.




I think the name of that grey stuff is Siliprene
