Re: Repairing chips in composite hull...
I have the original Wellcraft manual and Wellcraft promo guides. In all cases, it is touted as "DuPont Composite" or "DuPont Composite from the aerospace industry".
I don't think it is Kevlar by name, but it could have a lineage in common with Kevlar. I remember reading about various composites in boat hulls and while Kevlar was used, there are numerous composites.
