Removing 3M 5200
Debond Marine Formula lives up to its claims in second round.
Our recent test of caulk removers, (PS Tests Caulk Removers, Practical Sailor, January 2017), focused primarily on silicone caulk remover because these caulks can leave a residue that makes it impossible for anything to bond. After that test, we got a call from reps at Debond who explained that their product, although effective with silicone, is formulated to break the bond between to break the bond between 3M 5200 and a smooth gel coat surface. This is a common challenge for sailors who must disassemble through-hulls, remove chainplates, or repair structural components. So we went back to the lab to find the best antidote to 5200, and we present the results of our tests here.
