It depends a little on what type of finish you'll be applying. If you'll be painting it, it won't matter much. If you'll be staining or dying the wood, that needs to happen before the sealer. If you're just doing a natural finish... I'd rather let one of the more experienced guys handle that one.

EDUCATED GUESS: And that's ALL this is. Don't take this as anything other than my gut instinct. It would seem to me that it'd be fairly easy to tell if you're through the sealer ot not. The sealer makes it look wet, just like clear finish. I'd say that if anything still looks wet, you're not through. Also, I wouldn't think putting new sealer over any leftover sealer would hurt anything. BUT - you shouldn't mix finish types when possible, so if different things were used to seal.... I don't know. Sealer can be lacquer, shellac, or possible something else. I know you can use shellac to seal then put something else over it, and lacquer is it's own sealer...

Anyone else?
