I had two inexpensive wooden canoe paddles that had lost a lot of their varnish so over the winter I sanded them down and stained them. I was going for a two tone look but the stain did not take except where the wood was distressed. Made them look pretty distinct. Then I used Spar varnish, mostly three coats but six on the tips at least. First time I used them water was pretty low and we did a lot of shoving off the bottom. The varnish at the tips and a few other places blistered and peeled looking like sunburnt skin.
Now I plan to sand them back down and put G flex epoxy on the tips and tung oil on the bare wood as per a thread awhile back about refinishing paddles that came out after I had started the varnishing.
Thoughts? Did I do something wrong applying the spar varnish? I have never used tung oil and only know about it from reading here. How frequently do I need to reapply the tung oil and does it leach onto your hands while using them?

Evidently the wood was not sufficiently |

I use Varathane Spar Urethane on all the paddles I build and it works great. This product is water based and is the easiest, to apply with the best results of any finish I have ever used. You must allow it to thoroughly dry, which might take several days, even though it will feel dry to the touch in minutes. I usually apply two coats per day and after maybe 10 coats, allow a few more days to cure. I give it a coat of wax and it's good to go. Repairs are very easy.
That has not been our experience|

The guy who recommended Varathane to my paddling buddy and me (a boat builder with much experience varnishing) said it worked great for him. We followed instructions, let the stuff cure for days and it still went bad.

Rustoleum ultimate spar varnish (gloss). It is water based. I followed directions on the can regarding applying coats. It sat in an air conditioned room for about two months after finishing before being used, so it was thoroughly dried.
Well, I guess that raises questions|

...about water-based "spar" varnishes and other finishes in general.
I did not realize it was water based|

until responding to this thread. I thought spar varnish was for marine uses.
Spar varnish IS for marine use|
