Bottom paint Blister repair my vacation with West System
I know there is a lot of blister discussion but I figured I would post my experience and a question with regards to my usual practice of putting my boat in the water and the problems I have never had to deal with before.
My name is Ian, Sailing since 1977, a cruiser of the local bay and lately trying to learn as much as possible to maintain a larger boat and venture further away.
Every year I scrape, sand lightly, solvent the bottom and touch up. I have done this on 5 b oats to date then I got hold of number 6 last year a 1973 American Mariner 7.5.
A little power washing last fall revealed what I thought was gel coat pealing off and exposing actual fiber from the mat layer of the original layup. So a winter has passed and it is time to clean this up. I only have a short 3 days to do this and have grinded and sanded may way to clean hard surface fanning it out like a crater and then used West System epoxy 2 coats sanded between.
I am now considering using the WS barrier additive then a bottom paint?
I am a novice at this level of repair that I have attempted but am excited to have moved up a notch in experience. I have done through hulls, interior paint, wood and wiring rebuilt masts, but this is a big one and I need some advice on my last step and or any thing I missed that needs attention?
I will be pulling the boat this fall and properly doing the entire bottom I need to make this repair last this season. I repaired close to 100 spots from the size of a pea to the size of an orange. I usually use standard 100 dollar bottom paint, I am wondering if I should use the "wear away multi season" to better protect or just spend more on the barrier job?
Thanks sorry so winded
