So I purchased a 2010 Platinum the other day. I was really excited that it came with a hard folding bed cover from Extang, as these cost over $700. The excitement soon faded when I noticed that after a day of raining the bed had quite a bit of water in it. I began doing a little research and found that the internet is full of reports about these tops leaking. I then started inspecting the cover and found that foam pieces where the cover folds were dry rotted and were falling apart.

Turns out that before I noticed the leak I had already ordered weather stripping for sealing off the tailgate, MAXSEAL tailgate seal (also by Extang, just noticed that)

Its a hollow rubberized foam seal that attaches using 3M tape (same as vent visors use). After finishing with the tailgate I had a large piece of the seal leftover, so I decided I could use it to replace the damaged foam pieces on the cover. The foam pieces were actually very easy to remove using only a razor blade. Then just cut the new weather stripping, align and attach. The new piece is shown at the top of the photo.

Both pieces changed

Now, when closed, the top actually seals.

So far it has held up well against a continuous spray from a water hose. I'll just have to see how it holds up against rain while driving, but I'll keep you posted. All said and done I spent a little over $16 and about 30 minutes of my time.

PS: I have read about these tops leaking between the panels. This fix will not address this issue, only the foam padding.

 

Moved and approved.
