Over the years, I have found quite a few paddles on the trails that I have portaged. I live too far north for porcupines who love to eat paddles. They were all grey with only traces of varnish on them. Anyway, I took home about 10 of them and restored them by sanding them down, bleaching them with javex folllowed by more sanding and then a couple of coats of spar varnish. They turn out beautiful and are very ight. Everyone of them has a different length and I like them all. However......some of them had cracked blades when I found them. I varnished the handles but I painted the blades with a good quality bright red paint. The cracks are still visible. I would like to add fiberglass tips to my paddles.....especially those that have cracks. Is there somewhere any info about how to put some fiberglass and epoxy resin to the ends of the blades?
