Money well spent on the sandblasting... especially if you intend to keep the boat for an extended period. Yes, it's painful to think of the extra plating, but it is the right thing. My welder is proposing to cut holes in the patch in order to access the hull so that the plates can be welded directly to the hull and not just along the perimeter... once this is done he will glue the plate on with West Systems 5200, in order to seal out air and water from the bilge, then weld to the hull through the holes and around the perimeter.. I believe it's a good plan...
Two other things to consider... That Capac system should be well researched. I have been advised that these units can cause as much destruction as protection. I am lucky in that I live in an area with a Naval Labratory. Jim Preston is a retired engineer who lives here and is nicknamed "THE CORROSION GURU" for the Navy. He has a small firm and has viewed and measured the boat and is charting sizes and locations for placing Zincs on the boat. Once all work is done, they will splash the hull and let her sit for 48 to 72 hours. There is a technique for measuring corrosive activity at this point and once they take certain measurments, they will adjust accordingly. I will be happy to share his findings, but remember, for the most part, it is a bit of a WAG..Wild Ass Guess....
Another approach for me, being that the boat will be in saltwater is a fiberglass "Sandwich" to isolate the thru hull fittings. They are going to cut a hole in the hull just larger than the thru hull fitting and then sandwich several layers of fiberglass in order to keep the dissimilar metals from contacting. I think it's a novel approach... once again, this is a WAG approach, but does make sense...
I am still much a novice in this, but not in upgrading and utilizing new technology to enhance our older beauties.....
Finally, the only thing I can think of as far as posting pictures would be to post them on your own website and then providing a link here...
take care
