I recently purchased a 1987 Macgregor 26D which needs some work. There is a rubber trim that runs around the boat I am assuming covers the Hull and Deck seam. If one wants to ensure there is no leaks can you take this trim off and inspect/reseal under the trim and then replace the trim.Also - what is the nautical name of this trim ? Is it adivseable to remove and check /re-do sealing then replace this trim or just place sealer on each side of the trim. Thanks in advance for your help.
