I uncalked my tub, cleaned it very good, dried it, and recalked it using GE silicone calking. I also put a tub strip over the calking after it had dried for 2 days. I used tile adhesive to make the strip stick then I put calking around the top and bottom of the tub strip so that water would not leak behind the strip and mildew between the strip and the calking. The silicone calking is very elastic and is not rubbing off. It is very hard to clean it without it coming off. HELP, HOW DO I SEAL MY TUB????
