Practical Sailor tested caulks for teak
decks recently, and teak decking systems caulk came out on top for ease of use ( one part, no primers required) and longevity. I've never used it, but I intend to this spring.
The fein multimaster is great for caulk removal
- I've seen them used by other sailors and they make short work
of removing old caulk. My wife bought me one as a gift this past Christmas
and I will be using it this spring as well.
