varnish for wing spars

powers · Post by **powers** » Wed Oct 31, 2007 21:53

Any tips on varnishes for my new wing spars? I've heard that marine varnish is good. Some people have suggested home depots best. Any ideas?

2-part Thats the key. 1 part varnish, like Minwax or Spar-Varnish doesn't have the service life, and can be lifted with solvents such as MEK, acetone etc... 1-part will eventually start to fail and flake off as well.

The covering process you choose should have something or recomend a product. PolyFiber and Randolf both use EV-400, their homebrew 2-part epoxy varnish.

Thanks! I've been looking at the EV-400 product. I just did not know if 2 part epoxy was necessary. I'll order it in the morning.

I use the West Systems epoxy. They have a product designed for wood protection that will not bother the glue joints.

Mr. Hammond I see that you are located at GA2. I'm only about an hour drive from there, and I'll be looking for hangar space when my plane is done around March. Is there any Available?

Its better than hearing "Honey, is there anything I can do to help you?" because you know that she needs something that is going to cost you a lot of money! Shoes, handbags, watches, diamonds and so on...
