    I have just finished my fake granite kitchen countertop and I'm about ready to put the above-mounted sink back in place. I've read that silicone should be used to seal the sink to the countertop, but the sink is going to have to be replaced one day (I'd do it now, but I don't have the money...) and it's a pain to remove silicone caulk. In fact, I doubt that I could remove the silicone without damaging the countertop finish. So, I'm wondering if there is anything other than silicone that will provide a good seal, and would be less of a pain to deal with if/when I need to remove the sink. I was thinking of using polyseamseal---I used that under my toilets and it seems to have held up well. Whaddayathink?

    The clear polyseamseal works well for an overmount.
