So I have an offer out on a boat that has had a barrier coat applied at some point. There are currently no blisters
on the bottom but my understanding is that once the boat is cruised extensively in warmer tropical waters, this may cause blisters
There are lots of layers of paint
on the bottom that is flaking off but the bottom probably has not been painted in 5 years. I would like to soda blast the bottom to remove all the built up layers of the paint
and its my understanding that the soda-blasting will not effect the barrier coat.
I was thinking that I would then apply an additional four layers of barrier coat before repainting.
My question is this: can I apply new barrier over old barrier?
