Not to use on plastic windows
We used it on a plastic caravan window with a six inch crack, worked in fine rain but the heavy downpour over the weekend and it poured in , so I'll have to try something else

Does the JOB !
Does what is says on the tin, give it a good stir and paint it on with the free mini paint brush. I used it in my shower cubicle and it has worked really well. GIVE IT A COUPLE OF COATS and bobs your uncle ,sealed and waterproofed.Well worth the money.

Great sealant, easy to apply
It's a bit gloopy and runny, so ensure there's no dripping on areas you might not see. Brush washes off easily with soap andxwater
