[C320-list] Sealant/caulking

[Jeffrey Brown]

I'm replacing a few of the stanchions on my boat and wondering what type of sealant or caulking you would recommended. When I pulled out my top hatches several years ago I just used outdoor caulking from Home Depot  and don't have any leaks but now that Im not so naive I'm wondering if the high end 3m sealant from west marine is worth it. Hate to buy a huge cartridge for such a small amount that I need.
