Tanzer 16 seat patch finished -- November 5, 2015 -- To finish off the patch, one layer of cloth was added on top the mat. Then sanded the last layer of build-up back so it faired in with the seat surface. Now for a couple of coats of heavy primer, and it will be ready to paint. Started filling the holes and dings. After 40 years, it will take quite a bit of fussing to complete before painting. While the resin was mixed we also filled in a few factory "owies" in the gelcoat.
