Anybody been using the OSI Quad caulk for more than a season or two? If so, how is it holding up?
I re-caulked the deck when i put the boat back together in 2007 and the caulk still looks good.
That is encouraging. Also with Twin Cities apparently recommending the OSI Quad as a replacement for the OEM caulk, makes me think its a very viable solution. I doubt Twin Cities made that decision on a whim.

OK guys-
I'm following the thread on deck caulking..am confused.
One says use OSI #450, ones says Starbrite,but no longer available..what is the definitive product to use on my deck cover? I have a 1988 outrage 18 and do not plan on raising the deck any time soon... I just want the present caulk to look better. That presents another question...which caulk will adhere to the factory stuff? Thanks,
John
Starbrite does not make the correct color, so your choice is OSI #450. I would not try to caulk over what is there, you would be better to dig out the old stuff and replace with all fresh. I know it's a pain but it's really the best option, then you will be done for awhile. If you don't then when the old stuff cracks under the nice new caulk, and the new caulk cracks because of it, you will post on WC how the OSI caulk didn't last. Take the time to do the prep work correctly and your repairs will last a long time.
Starbrite makes a color called light beige which is a fine match unless your boat hasn't faded in the last 25 years or so, most have, and the color they used back then is just too dark. Call the company directly to oder, it's about $12 a tube.
It is fine, and smart, to caulk over existing caulk that is in good condition. Removing all the old caulk that still remains bonded to the boat is silly. Just make sure the old is clean and dry.
The silicone caulk BW used does not crack, it pulls away from the sides, expansion and contraction.

I guess I'm just silly but I'd definitely take it all back down to a clean surface before re-caulking. I assume anybody re-caulking is doing so because some of the original failed. Leaving any of the old stuff in place just doesn't strike me as a sound idea.
