The 5.7 is undergoing a major refurbishment after the skeg hulls wore through the bottom last year. So far, I have fully re-glassed the bottoms with Kevlar and West Systems epoxy, and the fairing is underway. Also fully cleaned up the gel coat with oxalic acid, and am doing gel coat repairs where it is crazed or cracked. All the decals are stripped and the hull is sanded.
Gel coat is still pretty good on most of the boat except where repairs along the keel line have been made, a hole repair on the left hull and some minor burn-throughs where sanding out the crazing took out the thickness. I'm trying to decide on using gel coat or paint to finish. Gel coat is far more durable and is more difficult. I would esitmate needing at least 3-gallons to cover to .2 mills over both hulls. In reality, I would shoot the upper surfaces thinner. This is followed by sanding, finer sanding, compounding and buffing. Paint would be faster and cheaper and not as durable.
I would really like to hear stories from any owners that have done this in the past, recommendations, and things to watch out for. Thanks,
Tom
