My DH made me a walnut bookcase when we were 1st married. It has only had paste wax on it, it is in garage now but I used to just wax it if it started to look dry. Polish is very different than wax.It might gum up. Could try a little on back side where no one sees it & wait 10-20 minute & see how it feels or if it is sticky or gummy. If it were just paste wax on walnut there might not be any stain on it or if there is the stuff in some polishes(if it says clean & shine) could damage the finish. I'm not a Guardsman user or don't know anything about it. If you got some try a little spot on back side for short time & if it gets gummy or sticky wipe off & clean with Murphy's oil soap in that 1 spot. At least that is what I would do.

A wiping poly varnish is great for what you want to do. That Finishing 101 link will tell you more. Duane Collie

if wood flooring isnt acclimated, isnt tested for mousture equalization to the area, isnt tested to ensure moisture content is within minimum recommended standards, and the interior building products as well (subfloor) isnt moisture tested, its a failure waiting to happen. It might fail and might not fail. it's a gamble ... Do you want to gamble ? Also, the enviroment should be set and stable at the time of the acclimation period, installation, and throughout the life of the product. In other words, it should be the average enviroment temp and humidity expected for the life of the area ... not just the hardwood and the area, but the subfloor as well, so yes, the HVAC should be opperating under settings normal for the entire acclimation period and installation unless manufacturers/standards-assc says otherwise, else there could be a dramatic negative effect on the flooring when teh climate does change after its turned on. For instance, it its humid and the wood picked up humidity, you can have gaps later when the hvac is turned on and drawls out the moisture. OR if the subfloor is too moist and the wood is dry, the wood can pull moisture from the subfloor and case buckling or cupping. industry standards exist because they are tried and true methods to ensure problem free installation and to protect the lifecycle and ensure the flooring product will perform as expected over the course of its life. in the end it doesnt matter why they were not adhered to if there is ever a failure, because, in the end, its still a failure. Then everyone has so much fun playing the blame game. alot of bad things could happen. nothing could happen. its best to play it safe. you might want to do some reading here: Here is a link that might be useful: National Wood Flooring Manufacturers Association - publications

Here's a picture. It's kind of dark in the room right now. It's a pretty honey yellow pine. Above the two drawers is another drawer without pulls. It's obvious that the piece was stained dark at one point, trying to simulate a fancier wood. There's reddish stain in places and all of the bun feet are stained, with the rear one being very dark. The pulls are wood with little metal flowers in the middle. Now, I need to figure out how to fix the drawers. P.S. If anyone is interested: They also had a bed for sale in tiger oak with really amazing turned spindle posts. Haven't been able to find anything like that online.
