Last tried was DAP Kwik Seal, kitchen & bath caulk.

Friend of mine doesn't have internet. Has stripped it out 2 or 3 times... mold reappears in 3 months or so.
Wouldn't white 100% silicone work? They've tried different products... don't think silicone yet.
Ideas?

Thanks,

Yeah! Let's try a Silicon Caulk. Why not kill the mold with bleach and then recaulk using a mold resistant caulk. Check it out at;Caulking: DAP 18306, review G.E. Silicone Products, Dap, Incorporated (http://toolsmet.com/caulking/8.html) Good luck, Tom

Thanks Tom, will check that site out & compare with what he's used. Water has been getting under it, so killing with bleach is a good idea with some better product.
