Q: I’m getting some shiny areas in the finish after four coats of satin lacquer, scuffing with 180 in between. The sealer over the pore filler is two coats of tinted garnet shellac. Over that is one coat of sanding sealer. I fear I’ve sanded through the lacquer and gotten down to either the tinted [...]
Q: Short of sanding it off, is there any way to remove a polyester finish from guitar sides?
A: Yes, but it might be faster and easier to sand or scrape it off. For guitars with solid sides, you can make the job easier by working it off with a heat gun. When heated, polyester tends [...]
Q: How do I clean the bare wood on new pine windows?
A: I suppose that depends on what is on them that you need to clean off. Usually, new items are clean and only need to be sanded. If they are dirty, choose a cleaner based on what is on them. For instance, dried surface [...]
Q: I’ve tried Zinsser SealCoat on wood turning as a sealer before wipe on poly. The finished result is outstanding; it did a great job of sealing spalted maple. For sanding, I use a 2″ disc in a cordless drill on low speed off the lathe with 400 grit paper. The sandpaper builds up with [...]
Q: I’ve been using cellulose sanding sealer on my woodturnings. What’s the difference between it and Zinsser SealCoat, and which is better? I normally use wipe on polyurethane as my finish.

Q: I have wood paneling in my shower stalls that need re-doing. I have already sanded and wiped the walls. What would be the best sealer to use?
A: Best? The best would be a moisture cured urethane, but it is not easy to come by. Offhand, I know of only one company in Brooklyn, NY currently selling [...]
Q: My friend has a tile kitchen countertop which has an oak border around the tile. The oak trim for some reason has always been tacky to the touch, as if the finish had never really set up. I was wondering if you had heard of something like this and if there is a way [...]
Q: I have an old guitar that I am partially re-finishing. The peg head has what appears to be a very dark rosewood veneer. It was originally stained with some form of opaque stain that lightened the color substantially to a very warm brown color, yet emphasized the wood grain very nicely. The stain was [...]
Q: If I wipe on too much Rockler gel polyurethane, I get streaks, and if I wipe on too little, I get ridges. How do I proceed?
A: I think the term wipe on is what is throwing you. The best way to work with it is to scrub it on liberally with nylon abrasive pads, [...]
Q: My floor is half sanded with some shiny areas and some bare wood. Do I have to remove all of the old finish before refinishing?
A: Yep
Q: I recently made an octagonal table top out of leftover red oak flooring. I wiped an oil based red mahogany penetrating stain on the sanded, raw wood. When [...]
