Re: Sand Blasting
Patrick McAneny
James, There was one area ,about 8 sq. inches where there must have been a void where the first or last layer of fiberglass was partially removed ,the manager said that sand blasting would have opened it up as well. It will be a simple fix and I will be doing about three or four coats of barrier coat . There is no other area where all the paint was removed ,so no damage to the gel coat,after a light sanding the gel coat is as smooth as can be. The yard did not consult with me on power washing as opposed to sandblasting ,which concerned me ,but I am glad they went with it.
Thanks,
Pat

This sounds like an interesting option to me and apparently there was no damage done to your gel coat. I like the fact that you avoided using harsh chemicals. You also checked your boats bottom for loose putty and voids in this process whether you realize it, since 5000 PSI can take anything off that is not well attached and can open up voids near the surface! I had the bottom of my boat checked with an ultrasound during the initial surgery looking for voids, delaminations etc. and non were found. That would not be the case on many non Amel hulls. It seems that Amel does a very good job with their laminations in getting out all of the air, especially at the critical gel coat interface. Really glad that this worked out for you.
