Have an anchor locker lid that has cracked beside hinges. Pathfinder boats have vinylester
and polyester resin used. Is it ok to put polyester resin on vinylester? Don't have info if vinylester is used in making the lid.

Thanks,

JMP
 
Vinyl ester resins are used primarily as structural resins and and are often covered with polyester gelcoat. The two are generally completely compatible, so shouldn't be any problem. Normal repairs for cracks and the like would use polyester resin fillers and gelcoat on top - a standard repair.
