Tips to stop a leaking tonneau cover

13008 Views 8 Replies 7 Participants Last post by  edubs77
I just installed a Bakflip Fibermax Tonneau cover and I cant get the thing to stop leaking. I know it's not suppose to be 100% waterproof it is always wet inside. I've readjusted the side rails, the cover, and heated the rubber seals on the side so they sit flat. Besides covering the thing in duct tape, I've got no more ideas on how to get this thing sealed.

If any members have had this problem, how did you get it fixed? Pleaseeeee HELP!!!!!

I have a BakFlip and it doesn't leak much, even in heavy rain. The drain tube(s) aren't kinked are they? They are kind of critical to keeping a lot of the water out.
buy a different one :shrug:

The drain tubes are fine and are routed out through the holes in the bed liner. Water is coming in near the wheel wells.
Find the source of the leak.

Get inside the bed with a flashlight and have someone spray the outside to pinpoint the exact area of the leak.
Laying some newspaper inside the bed can help identify the source of the leak(s). Until you've identified where it's leaking from your just spinning your wheels.
When I put my tonneau rails on, I placed some foam weatherstripping underneath -- sounds like this might solve your problem?

Sounds like you've worked through quite a few possible resolutions to no avail...I say contact the manufacturer for advice/assistance. If that doesn't correct the leak/seal problem - send it back. These cover's aren't cheap and if it's not acceptable - you have every right to refund. Good luck!
Thanks for all the tips guys. Im not sure what happened but the sides rails arent leaking anymore. The problem I have now is at the bulkhead. I guess the previous owner had a different tonneau cover on and cut a notch in the corner of the bedline by the bulk head and in the tailgate protector. Ill post pictures when it's not cold as balls out but in the meantime, does anyone have any ideas on how to seal these gaps?
