I need to seal around an inset kitchen sink. Tried wickes clear and it goes white when wet. Will this do the job for me?

Yes... good stuff for that or Sunday poly is also very good... different colours. . White is the most popular.

I used this product to craete a seal round an outdoor 1 metre square manhole 'drain cover' over a year ago and it has not 'degraded' at all since it was applied. I might be wrong, but I would be fairly confident that it would stick glass pretty well. Care would be needed to avoid 'smearing' the glass tho' as it is very 'smeary and sticky Black rubbery stuff'. Good Luck.

Would this stick a rubber seal to a runner for bifold doors?

I’m not sure, I used it to seal around my sink area. I don’t even know if it’s waterproof but it works and is still there a year later .

Is this okay to use with leds?

Hi, it shouldn't be a problem to use with leds.
