When we bought the eagle there was rot under the four salon sliding Windows which was non structural support. I cut out and replaced the wood, epoxy new structure and at the same time replaced with dark safety glass. The hardest was taking the teak frame a part without breaking damage. I saved the old wood to use as templates for new. Its much like repair replacing plaster board in a house except you use epoxy instead of plaster. Not that difficult.
We liked the California with the large salon window for plenty of day light. The large salon window is what we like about the eagle. Shot if I a yuppie metro sexual can do it it can't be that hard. Oh, I did ruin a set of cloths and a manicure several times.
