Extends the useful life of rubber seals. Produces an anti-static, water-repellent, protective film that aids in guarding against premature deterioration while producing a dry, smooth surface that reduces excessive friction and wear on slide-out seals. Compatible with all rubber seals as well as their adjacent surfaces such as fiberglass, aluminum and vinyl. Seal Treatment 17-ounce (US only).
The product itself seems fine, but when I received the rubber seal treatment, the packaging was a bit crushed. Luckily, the bottle wasn't leaking. I haven't tested it yet, but I'm hoping it works as advertised.

Seals are holding up nicely!
I bought this Thetford 40015 seal treatment for my boat. After using it, the seals are much more flexible and I haven't noticed any leaks since. It's easy to use and the 17 oz bottle goes a long way. Worth every penny!

Decent product, but could be better
The rubber seal treatment does its job, but I found it a bit messy to apply. It worked well on my camper seals but took longer to dry than I expected. Still, it seems to help prevent leaks, so not a total loss!

Great for RV maintenance!
I've been using Thetford's rubber seal treatment for my RV and it's been fantastic. The 17 oz size is just right for multiple applications. My seals feel more pliable and it's easy to apply. Definitely a must-have for anyone who cares for their RV!

Stopped working after a few uses
I was really looking forward to using this Thetford seal treatment, but it stopped being effective after just a couple of applications. My seals aren't holding up as they should. Disappointing for a product that seemed promising.
