I have made a pair of paddles for every canoe I have restored and have always finished them with spar varnish with great results. For the last two canoes from this winter, I decided to finish them using an oil finish. The paddles are ash, were sanded from 80 to 320 grit by hand and sanders. They were then wet to raise the grain and sanded using 220 grit paper by hand. I did this wetting process twice. I then used Baer Tung oil on them; brush on, let sit 45 minutes, wipe off and repeat after 1 hour. I then let them dry for two days outside after which I rubbed them down and reapplied oil twice more like the mentioned above and waited another week before a final wipe down. I took them out today for a paddle of about 3 hours and while loading the truck, I noticed the grain had raised slightly on the blade from water contact. After the drive home the grain had lowered somewhat, but not to the smooth finish before using them. Any ideas on what I am doing wong and how can I correct this? Thanks for any input.
