Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: Deck seam caulking recomendation

Well, looks like I need to re-caulk the deck seams on my 2000 Dautnless 220. The seam I am talking about is the one that goes around the fuel tank access deck and runs all the way to the stern of the boat. I noticed yesterday that the seams in a few area, especially at the stern at the rear steps are separated leaving a gap.

So, I am looking for recommendations on what type/ brand of caulk others have used with good success. In doing research, the two that seem to be showing up most frequently is 3m 4200UV and Lifecaulk. I am looking for a lasting quality product that will be somewhat easy to get a nice smooth factory finish look. Spoke to Whaler and they just said white RTV is what the factory uses.

Boat is located in Florida and stays covered on the trailer when not in use.

Any tips/ tricks of the trade are also greatly appreciated!
Thanks in advance,
James

3M 4200 is a combination adhesive and sealant.

Lifecaulk is a sealant.

While some disagree, I only recommend a polysulfide sealant for the seam and for under the head of every screw.

For those with a Desert Tan gelcoat, there are several exterior siding caulks that come close to a color match.

There are various suggestions on applying a smooth bead. My personal experience is to use a small cut in the tip of the cartridge and make each side one continuous run without stopping or removing the tip from the seam.

Phil I agree Boat-Life Lifecalk is the way to go. I used it for yers on all my antique and classic wooden boats repair without a failure.
I do believe Lifecalk now has several different colors available and maybe the teak color would work.
