Temp fix for leaking through-deck fittings

[voxxmd]

Bought a boat 18 months ago. A solid boat but there were numerous leaks at the fixed portlights and at most through-deck hardware (stanchion bases, chainplate, etc.). I replaced the portlights and they're good, and was planning to next attack the through-deck leaks with the full-fix (remove hardware/extract wet core/epoxy holes/drill new holes/rebed). However, just bought another boat (with no leaks!) and planning to sell the current boat as quickly as possible.

My question: Are there any decent caulks/sealants I could use to use to temporarily stop the leaks, yet are reasonably easy to remove if/when the new owner wants to tackle the full-rebedding project?

Thanks,
Michael

Butyl Tape would be best, if you're able to apply it (depending on your fittings, etc). It's also removable with some elbow grease if needed, but seals excellently.

There a product called "creeping crack cure" or something like that, which surprisingly works pretty well...
