Shiva was 25 last spring and there was a fella at the yard where she was stored on the hard
that had started a soda blasting biz. I had 25 yrs of bottom paint and figured it alone weighed hundreds of pounds and it would... if nothing else lighten the boat.
The blaster was new at the game
and honestly no too careful. He oversprayed the boot stripe - and so I had to re do that as well as the bottom. He was also a little to aggressive and dimpled the bottom which required an awful lot of time fairing with expensive epoxy
of course was in good shape and did not need to be blasted and blistering wasn't even an issue. He took that down as well and that too required lots of fairing since he blasted out some of the fairing.
Once he was done... I had to take over and the fairing was a huge task taking many days... expensive epoxy
fairing and lots of sand paper.
Once that was done it was multi coats of Interlux
epoxy barrier coat. Again, an expensive product.
Finally - remasking and applying the bottom paint and then... remasking top and bottom this time and applying the boot stripe after more sanding
and fairing. This was another multicoat operation with Interlux
I went through 100 rubber gloves many roller sleeves, tons of sand paper, solvent, protection suits, rags, masking tape.
I then decided to tackle a repair of the rub rail. Wax and then launched on June 30... latest I've ever gone in the water in 25 yrs.
They blaster said he removed over 500# of paint which was mixed in with the soda.
The boat was so fast and slippery when we sailed her the first time. WOW. But this is a once in boat's life operation. We had no blisters, but I wanted to remove the 25 layers of paint and get the bottom smooth and fair.
Way expensive, lots of hard work... worth it? Probably not if you don't have blisters and are not racing
. I'm glad it's behind me
