SS by Gem or Marine Part Depot.

I'd also recommend LifeCaulk by BoatLife - very similar product, but a MUCH better value than any 3M product in that the tubes don't turn hard and unuseable before your next use ...

Take your tube of 5200 and put it in your garage fridge. I have read where people put screws in the end. I just let it harden in the gun overnight, with just enough pressure so as not to suck back in the tube. Next time I need a little, pull it out the fridge and poke a little hole up near the nozzle on the side of the tube. Leave a little pressure on there so it doesn't suck back into the tune. Stay up near the end of it will cure a piece and you can't get the plunger by it. I'm on a 4 month old tube, and it doesn't really seem to suffer.a
