Mildew under Cetol
I spent hours stripping and refinishing the wood seats and combing on my sailboat.
I took it down to the bare wood, put three coats of Cetol on it and it looked good.
I put a tarp on the boat over the winter and I think it was too airtight.
I just uncovered it and the wood seats are covered in mildew, mostly where the grains in the wood are visible.
Why wouldn't the Cetol have sealed the wood enough to prevent moisture from getting in?
Do I have to sand all the wood down and start again?
How can I prevent this from happening again?
It looks awful!
