I'm finishing my first woodworking project — a tabletop that I hope to mount on a sit/stand desk mechanism.
I've stained and applied 4 coats of Varthane water-based polyurethane in matte finish. I applied each successive coat after lightly sanding between coats with 400 grit sandpaper and achieved a finish I'm pretty content with. I'm now on the final steps and have a couple questions...
I'd like to apply a final protective barrier and achieve an ultra-smooth feel to the hand. I've read about using #0000 steel wool and polishing with automotive wax or carnauba wax. However, I'm a bit conflicted with some people advising against steel wool on a water-based varnish. I've also read in other forums that steel wool is not a problem on water-based varnishes as long as it is used on the final coat and it has been thoroughly dried. Can I use #0000 steel wool as a final polishing step? If not, what are my alternatives? I've read mixed reviews on synthetic wools, do you recommend them? What course grit?
Any recommendations are welcome. Thank you so much in advance!
