Trying to fix some hail damage spots on hot tub cover

I have used this on my boat and hot tub cover

We used this on our spa lid and its protective cover after the birds and seaside weather caused several holes.

So far so good for hot tub cover.

I noticed that there was still a bit of air leakage, but overall the holes in my mattress were well covered.

used it to seal a seam on my hot tub cover so far, so good

Purchased this to repair a small tear in our hot tub cover after a limb fell on it

My new puppy chewed the edge of the hot tub cover, leaving about a foot of edge missing and threads hanging down

Our hot tub cover was badly damaged after a severe hail storm 3 months ago

Thanks so much, I didn't have to buy a new hot tub cover

Used on a hot tub cover that had a two inch tear from a fallen tree branch.

After a wind storm last winter, I found the 2ft tear had gone from the stern, all the way up to the bow window, almost splitting the cover in 2

We used this on our hot tub cover.

This product is just what I needed to fix my hot tub cover

Bought this to cover cracks in my hot tub cover that were leaking when we get an occasional rain here in Phoenix
