Found this info at KilmerCreek.com (They make outdoor cedar furniture). I like the idea of polyurethane with UV light protection. I need to find which ones can be used indoors.
POLYURETHANE: A great looking finish is semi-gloss polyurethane with UV light protection. The polyurethane will place a very hard finish over the wood. Easily resists water, chemicals and grease. Won't crack, peel or stain; and covers the grain well. A UV stabilizer is incorporated to protect it from breaking down in sunlight and to protect any underlying stains from fading. The cedar will slightly darken, but will give the wood a very rustic, yet very traditional look. The warmth of the red tinge really comes out nicely. However, this finish needs patience to apply, two coats are recommended, and to refinish will require sanding.
TUNG OIL based MARINE VARNISH: A better application for cedar that will be exposed to a lot of liquid water or for direct sun applications. Marine finishes have more UV inhibitors and can better stand direct sun than most spar varnishes. This finish will be double to cost of most other finishes. In a liquid environment, expect the varnish to last 2-3 years.
VARNISH: A clear varnish can be applied. Varnish gives a hard finish, a beautiful shine, and a more natural look than polyurethane. The finish can easily be repaired, but when applying the varnish allow proper time to cure the finish.
I am going to check out Lowe's and our local paint store to see what they say... will get back to you.
