Best clear coat for pine interior window sashes?
I have Andersen pine interior (vinyl clad exterior) low-E windows. I have used Minwax oilbased Wipeon poly on the jambs and stools, as well as all the interior trim. Some pieces I have stained with Minwax gel stain to even out the color. Now is time to do the sashes. What is the best clear satin finish to use on those? I used Sikkens Cetol Door and Window on the exterior side of the (fiberglas) front door, would like to use that on the sashes b/c of the UV inhibitors but Sikkens not to use on interior woodwork. Should I just use the same Minwax poly I used on the trim? Much as I hate to stain the sashes (and get the stain pooling in the corners), would a coat of gel stain help with UV protection? I have one south-facing window that is already showing a little degradation on the bottom sash so the glass isn't blocking everything. Thanks.
