Hi Joan,

I think that the idea of grinding or course sanding is the best way to go. As you have damaged the actual hull you will have to sand or grind anyway so you might as well be done with both problems in one procedure.

Don't just re-glue the damaged laminate. Cut and grind the broken pieces away to the undamaged part and do a proper layup to bring the surface back to original level.

Re-glueing is a rather iffy repair proceedure and a proper repair is actually easier and any fiberglass repair is pretty easy. Most commercial fiberglass uses a polyester resin so you can buy an inexpensive repair kit from your local auto parts or hardware store. Polyester is far cheaper than epoxy.

To keep the dust down cut as much as you can away with a hacksaw or even just a hacksaw blade if that is easier. Use a dustmask when sanding as well as long sleaved clothing, a hat and latex gloves. Wash the clothes immediately when done and have a cool shower which will help to keep the pores in your skin closed until the dust has been rinsed away. (Things aren't usually that bad but if you are sensitive as some people are, you will appreciate the extra precautions)

Ian is a opinionated, obnoxious, know it all who frequents these boards. He has a bad habit of telling everyone to use urethane adhesives!!

Nice to meet you. {:o)
