Silicone doesn't stick to silicone. If you did 3 thick lines, I hope it was 3 lines before they were cured. Also, the curing time is significantly longer. Silicone cures by reacting to moisture in the air, so the silicone in the middle will take a long time to be able to cure fully.KrankyKrab wrote: Yeh I know - I tested each side for 48 hrs. And I put 3 thick layers of silicone. Fingers crossed.
