I hope that this is not too off topic, but this group seems to be uniquely qualified to sddress this. My house (or boat) has cedar plywood siding and I need to recaulk between the siding and vinyl windows and arround the door frames. Do you think that it would be advantageous to use marine caulking (because of its flexibility) rather than the "home" stuff available at the big box stores? Thanks for your indulgence and advice.
