Re: More on Barrier Coating
Never heard of anyone removing their thru-hulls due to barrier coating. You will most likely do more damage removing them, especially if they are bedded well with 5200.
I removed two transducers prior to barrier coating because I was changing out my instruments and the existing transducers were not compatible. It was a bear removing them and had to destroy each unit.
I would go with your option 2 but be sure to protect your depth transducer ceramic face with a good 3M tape as the epoxy barrier will damage the unit.
