I walked up to the art store this afternoon. Was looking around and found something new - Krylon UV-Resistant Clear/acrylic coating. I read the label and it says it works on wood (and other things). I have some Osage Orange wood that turns brown when exposed to UV light. Thought I would try a can of this stuff. Have any of you tried this? I thought I would take a fresh cut piece of Osage and put Deft on 1/3, leave 1/3 unfinished and 1/3 with this new finish to see how it works. But I thought I would check with all of you and see if any have tried it?

Jeff - I have tried the matte finish - Krylon #1311. This is slightly different as it is labeled as a UV-Resistant and the Krylon # is #1309. I know that when I went to finish the doors on my house - the paint store and the contractor told me to use spar varnish as it had some UV resistant capabilities where poly and lacquer do not. This is the first time I have ever seen anything that is supposed to protect from UV light except paint.

The UV inhibitors in varnishes and other clear finishes are actually only good for retarding the breakdown of the finish itself. Any wood that is exposed to direct sunlight will still change color with the clear UV finish -- just a bit slower.

This is what I've been told too. But I haven't done any test with these products.
 
I haven't done an official test but I have a wooden rack on the top of my pickup and every couple of years I try a new clear finish to see if I can find something that will hold up. The rack is pressure treated pine dyed black so it really heats up in the hot sun. Nothing has held up so far. Spar Varnish and Epoxy have lasted the longest but both were getting cracks within 6 to 8 months and were toast in a little over a year. Polyeurethane, straight Varnish and clear lacquer didn't do well at all. The saga continues, I'm ready for the next product. Anyone have any suggestions?
