We have a hot tub, free standing not built in, that has cracked between two seats. Fiberglass repair kit didn't hold. Any idea how to fix this.

Thank you,

I don't know the answer to your specific question but I just wanted to ask if you are certain that you have no warranty left on the hot tub. The reason that I ask is because my neighbor has had his hot tub repaired twice now at no cost to himself.
The most recent time was when his daughter and about ten of her friends (7 to 10 yrs old) were in it and they broke some of the parts just by pushing and shoving each other around. The company repaired it with no questions asked and he hadn't even been the original purchaser as he bought it from a neighbor who was moving several years ago.
Maybe he just lucked out and stumbled into a very lenient company but I just thought I would mention that for whatever it is worth. Good Luck.

Thank you for replying. I may just check in to this since we bought it second hand from a friend. They never checked with the manufacturer. They just don't use it anymore and, didn't care about fixing it.

Thanks again.
