This silicone works even when water is present, and it apparently works under water. If anyone aint tried this then your missing out ! My merchant seen the rep fix a plastic cup full of water with a split in it and I used some the other day on a job 5 guys from my company had been to and it cured the problem no messing ! Available in clear,white and grey and it sticks anthing to anything i hear ! I rate this highly and someone shud of come up with this years ago Anyone else used this and opinions ?
