I’m finishing a white oak coffee table with polyurethane semigloss. Generally use ScotchBrite green pads for the between-coat scuff sanding. Question: how do I know when I’ve “scuffed” it enough for the next coat?
Tnaks for Thanksfor the help.

I usually use gray pads. I think green is a bit too coarse. I rub out until the gloss is basically gone. I generally make an oil-based wiping varnish, and put coats on a few hours apart as they dry so quickly. Poly won't cure that fast so no sanding between coats is needed. Put on 3 or 4 coats in a full day, then smooth if needed and rub to a flat sheen the next day before putting on two more coats or so. Wipe-on coats are very thin, so you need 6-8 coats, but each is super easy and fast to apply. Wait a couple of weeks and buff with polishing compound for a super finish.
Best of luck,

*Hi Rod. I use shellac whenever I can because it's so simple and fast to apply. Sometimes, though, it's just not durable enough. It sounds like your varnish is fast, simple, and durable too. Would you mind sharing your formula? I'd like to try it out.Thanks! Joel Watson
*Sure. See http://www.gis.net/~dheaton/woodworking/woodworking.shtml. There is an article at the bottom of the page called "Finishing Notes". The finishing notes end with some links to some great sites for further reading.- Rod Cole
