Easy Do-It-Yourself Canoe Repair Using Fiberglass 

Where are you located? The stuff I use might not be available to you.

Sand the wood until bare to remove old paint/varnish. If you use polyester as the resin then use the following layup: 3/4oz. CSM then 9oz plain weave cloth. You'll need to wet out the 3/4oz CSM on the hull then roll out air bubbles using a 3/4" X 4" spiral-bristle roller. You'll notice that as you roll it, the resin rises to the surface...you want that to happen. Now apply your 9oz cloth and bristle-roll it. Add resin in the dryer areas and keep rolling it with the bristle roller, but not so much as to have it drip. Once cured, paint on another coat of resin to give a smooth finish. Your last coat could be epoxy resin if you want. If you only want to use epoxy as the resin, don't use the 3/4oz CSM...the binder that holds the CSM together won't dissolve in epoxy and you'll end up with a chunky mess. Good luck.

@@Mofiac Hi, thank you very much for your advice. Looks like epoxy is better for water resistance and general durability, and the price is comparable to polyester (price being the main reason given for using polyester). Using 300g (10oz) matting without CSM is there a risk of the matting delaminating? Would the topcoat prevent that with the topcoat quantity being half the main matting quantity? Thanks again :)

Yes it will.
