The nice thing about marine sealants is one doesn't even have to get it all off. One can put another layer over some of the old and as long as the old bond is good so is the job. Can't do that with hardware silicone. At least, not in my neighborhood.

I've never had a problem with silicone sealants, probably because I throughly clean stuff when I'm rebedding, to the extent I usually wet sand gelcoat with a fine paper and then solvent wash before putting anything new down. And yeah, I can tell silicone a mile away. It's a pain to get the surface to take a new sealant, but in the larger scheme of prep work it's really not that bad.

I think as Jim put forth, it really depends on your process. The one really nice thing about silicone sealants are their durability, flexibility, and softness. In some applications they are a better choice than other compounds that harden significantly more
