I am trying to find a caulk which is compatible with Woodguard finish. As suggested by Sherwin Williams, I am removing old caulk, and using MEK to remove it in the cracks, but there will be remnants which could cause their urethane caulk to fail. Any ideas on what type of caulk I can use? Woodguard told me silicone or latex won’t be compatible.
