Flex Seal vs Leak Seal
I got a free flex seal spray can at the texas nascar race and finally got the chance to try it out. It is amazing stuff. Rust-oleum makes the same thing called leak seal. Got it at home depot. In my opinion, every rv should have a can on board.

Rust Oleum leak seal
I was able to purchase white Rust Oleum Leak Seal on sale at my local Value Home Center for 9.99. It is cheaper than the original Flex seal for 12.99 at Walmart. I will use it when the weather warms up. I have one pesky small leak at the top of my awning. I've tried many things and it still leaks just enough to be a pest. I will have to carefully tape off so it doesn't get near my rubber roof. This sounds like a good product to have in the RV as it fixes a multitude of problems.

Leak in Slide

Anybody who has a leak from the slide should install externbond tape along the top inside edge of the slide. Pull the slide in, and look behind the top trim piece. There are multible sheets of metal that form the top inside edge of the slide. when the slide is out this edge is up against the seal, water can get through weep through the seams of the metal and drip inside the RV.
A few dollars for the externabond tape cheap fix.

I couldn't post where this came from originally (too old) so brought it here. Would Flex Seal Rubber Spray be worth considering? It seems it would be alot easier to get in there and spray that when the slide is in?
Thank you,
Elke

Flex Seal / Leak Seal
Flex seal is awesome. Our coach is getting up there in the years. recently the seal product previously used on the top of our slide outs began cracking and falling out and our slides started to leak. I removed the slide awnings cleaned the tops and applied the Flex seal spray all around the top of the slide outs where the seal is needed and walah!!  no more leaks. Fast and simple. No RVer should be without a can of this.

Come back in a couple years and give us an update on its durability.

NOTE: It may not be compatible with EDPM roofing!
I've used it in a couple places at home and it appears to be good stuff. Not sure how UV resistant it is.

Don't even have to wait that long, try about 6 months tops.

UV light breaks down flex seal, I had the same experience!

These products contain petroleum distillates which should never be used on a RV roof, period.
A neighbor in our park pulled out 10 cans one weekend and I told him I would help fixing his leak instead of using those and I explained why.
Nope, I can do it myself and he proceeded. Roof still has a leak and it softened the roof up where he applied it. Now it has bubbles and a tarp over it as he tries to come up with another solution.
For other things, well it does work pretty good.
