## Questions & Answers

**Q: Do you get 3 for the price shown?**
A: No, there is only one, which makes it expensive; I would not have bought had I been aware of this. The photo is misleading.

**Q: How long does it take to set?**
A: Goes tacky fairly quickly, but give it a few hours to set.

**Q: Would this work to secure a gutter end-cap to the guttering on my roof? The end cap keeps being pushed off in heavy rain.**
A: I would say yes. As I’ve used it to secure spoilers on my and my sons van and to seal the windows on my shed so in theory should be fine aslong as the end cap is clean and dry when you glue it together. 👍

**Q: does it stick under water**
A: No --has to be applied in the dry.Gordon

## Customer Reviews

### ⭐⭐⭐⭐⭐ Incredible adhesive and very strong, endless uses for this stuff !
*by G***Y on 27 June 2020*

Incredible strength, this is one of the best PU sealer/adhesives you can get. I generally keep a tube in ready for using because it is so good, I used this tube on an old tractor which had perished and cracked, I pushed it into the cracks on the tread and the side walls ( I do not recommend doing this on car tyres, the tractor only runs at 10psi).I have moved over 100tons of rocks on hard ground and the sealer is still perfectly in tact.This sealer is similar to what the automotive industry uses to bond car panels on the vehicle and bond windscreens in and it sets like rubber with incredibly high adhesive properties, I tested it by sticking a strip of rubber on the trye in a place where it would get the most abuse and it stayed on in extreme digging conditions for a long time, I certainly didn't expect it to last more than 10 minutes but it lasted 2 days.I even used the spare sealer on some worn out gloves and they lasted better than when they were new!Any negative reviews are probably down to in proper application or silly things like receiving the incorrect colour as I have read!Important! This type of product will store for a long time if you use kitchen foil to seal the tube and store it in the fridge, I have done this for up to 12 months and still been able to use it.

### ⭐⭐⭐⭐⭐ Tiger seal but cheaper.
*by M***T on 17 October 2023*

Very similar to tiger seal, used this for bonding on a couple of side skirts.Easy to use, good adhesion and overall a decent quality gear. Just put on, put in place and tape to hold in place overnight if needed.Recommended!

### ⭐⭐⭐⭐⭐ Great quality product
*by P***R on 15 May 2024*

Absolutely perfect for re-sticking my boot sole back onto my Dr Martin boots. After local cobblers failed to repair them, this product was just the job perfect repair and flexibility boots as good as new.
