Ah... final finishing, started by sanding everything down with 80 grit sandpaper, then moved to 150 grit and then final sanding with 220 grit. In between each step, I watered down the paddle to raise the grain out of the wood, then let dry before then next sanding. I used a combination of a palm sander and sanding by hand, I have the Black and Decker Mouse which has a curved attachment and that made smoothing out the rounded surfaces much easier, easily done by hand though, sander just makes it quicker.
Once that was completed I used steel wool to polish up for the last step. I didn't put any fancy tips on the paddle or epoxy, just finished oh natural, using Tung oil, I brushed down the entire paddle and let dry for 24 hours, did 3 coats of this and voila... done.
I haven't tried the paddle yet and while far from perfect, it was not a bad first attempt, quite proud of it actually, certainly learned a lot and will do things differently on the second one for sure, highly recommend this project to people who just want to try it out, was quite fun. Plus I now have all the tools. Next one might be a laminated kayak paddle or just a regular canoe paddle.
Here is a picture of the finished paddle.
