Sikaflex 291i puncture repair kit!
I've just used this stuff to seal the screws and plates onto the transom for my new up and over wheels.
I had some left and I have a couple of tiny niggling leaks, one in the speed tube and one in the hp floor. Neither are a major problem but I need to properly sort them out. Anyway, I tried applying some 291i and unbelievably, after 24hrs drying, it works a treat even on the HP floor and that goes to 11bar!!!
Not a long term solution but saves a day out of the water making quality repairs when the sun is shining.
Now I can wait until it's raining again to do the repairs,brilliant!!!
