I did a search on this subject and got 759 hits. Too much detail to go through for a simple question. I would like to know what caulking to use in refreshing the original caulking on my motor home...
Apply Dicor "Caulk" by caulking the places that need new "caulk". Unless the old "caulk" is badly deterioated, there is not need to remove before applying new "caulk". Eternabond tape is also a good alternative.
