10 year old HB roof gel coat is showing signs of thinning spider cracks, no soft spots im aware of.
Have not used a moisture meter on any of the roof. Curious my neighbor is having his done with some wood replacement an is going to have a epoxy coating..... curious as to the pros an cons?

any suggested reading

I was wondering about this also. I think an industrial 2 part epoxy would be much easier to apply and probably more durable than a gel coat floor. I mean, that epoxy stuff get run over by fork lifts all day long at our plant and lasts for years!

More expensive. Gel coat can be colored to match your boat and is easy to apply.

You have to be really careful with the epoxy coatings. It is not about them being tough - it is about their ability to expand and contract without cracking. If I were going to use something other than gelcoat, I would consider Durabak which is a one part polyurethane. Gelcoating a roof is not that hard. Rough up the current roof using a rented drum sander, follow the instructions on mixing the gel coat and hardener, and apply with a roller. It is pretty simple.

My concern was the hardness factor too, the gel coat will give u more elasticity (sp) and we all understand the stress factors of a HB.

The sales person, for my boat, tells me Thoroughbred HB manufacture uses the same process that he applies.
Thats really not to difficult to confirm, as for as the chemical compound goes.

The above information was given to me today, I had already posted my question.
IM told the epoxy is a little slicker, i'll try an give Thoroughbread a call an see what they tell me.
