K2 BOND High Temperature 350° C Heat Resistant Silicone Sealant BLACK Adhesive 21g

It is quite difficult to apply and not so adhesive and no instructions how long before it takes. Put pressure on 2 things trying to seal together and only paty of the items bonded, and then only for a year.

Fixed Rocker cover oil leak on my lawn mower no problem.

Good value

Great product but over a week late on the delivery

Bought this to re assemble an oven door. I had to separate the glass from the plastic door frame and as this is rated at 350 degrees Celsius I thought this would be a good option. I removed the old black seal with a scraper blade and then thoroughly cleaned the plastic door frame with ipa (99% pure alcohol). Popped open the (small) tube of this and smeared it generously round the frame, popped the glass in and made sure it was in contact with this sealant. Left it in a warm place for 24 hours then used a sharp scalpel blade to cut away any excess. Put the , now repaired, oven door back and fired up the oven. I was expecting bad smells or for the glass to drop out, but no, all good. Been in use now for 5 weeks. All good. I also fitted a waterbutt last weekend and used what little was left to seal the tap / overflow joints. Again, all good. 4 stars as I can’t comment on longevity, and the tube is very small but seller doesn’t hide this fact. Order 2 tubes you will find uses for it. Take your time and prepare the area properly.Cheers.

I was going mad trying to find out why my car spare wheel well filled with water every time it rained. This was a serious leak but I was baffled!After going on some forums I found that a possible cause was the upper (3rd) brake light above the rear screen on the tailgate. I had not considered this being the cause being so high up.Apparently, it is a design issue with my vehicle and the gasket around the LED light perishes letting in water at the corners and the top. The water then runs down inside the tailgate to end up in the boot.Alas, the gasket is not available and the light has been redesigned such that the whole assembly has to be replaced. That costs £120+ from a dealer and even a used part is £60+ on the well known auctions site. This seemed a tad steep!!I worked out eventually how to remove the LED assembly - it was trickier than I had thought. However, once mastered it was straightforward enough.I initially used some black 'waterproof' silicon sealant from Halfords. This was a total failure as it refused to adhere adequately to the car metal body work and a small leak remained. I also had the 'joy' of removing it from the LED assembly itself.The reviews for this product looked promising so, without too much hope, I sent in my order.Well, this works a treat and the leak has vanished. Indeed, I have purchased another tube for other uses and to keep in my toolbox for emergencies!I have also used it to repair a thermostat gasket - so, it works well in hot locations too.So, this works a treat and is great value. You can save a few pence by purchasing this from 'other sellers' rather than using Prime. Delivery is just as quick - my 2nd purchase arrived in 24 hours and cost me less than £2.That's a lot less than £120 for a new LED light assembly! Excellent.....

Product was solid in the tube, completely useless , threw it in the bin

Bought this as I have cast iron pan supports on my hob that have small rubber plugs that keep the pan supports off the stainless steel hob and over time 2/3rds have been lost. I did contact the company but they wanted £5 for each of the plugs plus £10 postage!! No way was I prepared to pay that much so I did without for ages. Don't recall what prompted me to look at this product but anyway it's cheap and cheerful so ordered it. I did keep the pan supports upside down for 24hrs just to make sure it had set properly then put them back on hob and low and behold it worked!. Not sure how long it will last but there is enough in the tube to redo if needed.
