Try to make sure all existing moisture disappears inside. You might need to make the hole bigger to ensure enough air circulation to dry out all water moisture, it takes time to dry. You can patch the hole with fibreglass compound found at the autmotive section of Canadian Tire. The patch will be as strong as the fibreglass body itself. Sand and paint if you are finicky about the look. Edited June 1, 2012 by bassfighter Link to comment Share on other sites More sharing options...
aplumma Posted June 1, 2012 Report Share Posted June 1, 2012 If it is truly a pinhole you can inject it with superglue. If it is bigger than a pinhole then clean it out with a small drill bit and use fiberglass resin injected with a syringe and place a piece of plastic wrap over it to keep it from running out. Let dry and then remove plastic. Buff with sandpaper to remove all plastic. Any bigger then use fiberglass and resin as a normal repair. Sand and finish as needed. As a note if the area is wet inside you need to use a hairdryer to dry the inside or the patches will not hold I also have had success with a monitored space heater.

soobnoob Posted June 1, 2012 Author Report Share Posted June 1, 2012 Awesome. Thanks for the quick responses. The wood is probably going but will be a project for the off season. Link to comment Share on other sites More sharing options...
