It is a very good material for hull repairs.
They publish very good booklets on:
002-970 Wooden Boat Restoration & Repair
002-550 Fiberglass Boat Repair & Maintenance
002-650 Gelcoat Blisters: Diagnosis, Repair & Prevention

There are lists of dealers, US and elsewhere at http://www.westsystem.com/

All-

I know little about West System et al and boat hull repair. I need
some guidance and appreciate all the help I get. Thanks in advance.

My questions:
(1) What is West System? Is is a Polyester resin, a Vinyl ester resin,
or an Epoxy resin fiberglass repair solution?. How do these compare? I
am over simplifying the options?

(2) I have heard a lot recently about Vinyl esters as having good
properties. What are its pros and cons. If this is not what West
System is, from the experts, how does it compare?. Any reputable
suppliers?

Thank you.

Regards.
