Q: I built a box of marine plywood to attach to the underside of the roof allowing a column to be mounted. After three coats of acrylic latex paint, the majority of the box is a nice white. However, there is a zig zag in the side of the box which either won’t accept paint [...]
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: I’m restoring a Martin guitar, and after staining, I added three very
light wash coats of 1lb. cut shellac. I’d like to strike the pores black
with Finishers Glaze seal with sanding sealer, fill pores with Bartley’s dark, seal and topcoat. Martin mahogany pores are darkened nicely. I’m trying to do it the right way.
A: I’m [...]
Q: Is there any barrier coat that will allow me to seal waterbased finish on a guitar that has been plagued with fisheye problems, then spray with waterbased over it?
A: I won’t say it is guaranteed, but spraying coat of Zinsser SealCoat usually does an excellent job of creating a waterbased friendly barrier coat. Incidentally, [...]
Q: I decided to spray Deft’s new waterborne acrylic wood finish for the top coat on a guitar. I am not happy with the outcome. I seem to get small fisheye no matter what I do. I am spraying at about 35 pounds and thinned it about 25%. There are no contaminants and I have [...]
Q: If I don’t coat gold leaf, it will wear after a while, but when I coat the leaf I lose that brilliance. What should I do?
A: It is true that coated leaf is not as brilliant as genuine burnished metal leaf. That’s why real gold leaf is left unsealed. As for wear, that’s just [...]
Q: I’m currently building an outdoor grill cart out of ash and obviously need to protect it. I was thinking about sealing with Zinsser and then multiple coats of an exterior finish. What do you think?
A: You did not say which Zinsser product, and only some of their primers are exterior coatings. For instance, SealCoat [...]
Q: You said we could glaze gold leaf. If we apply glaze directly over uncoated leaf, won’t it tear the leaf when we clean off the excess?
A: No. You simply wipe off the excess glaze immediately, while it is still liquid, using a soft cloth, or blend it using a very soft bristle brush. Neither [...]
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’m refinishing a mahogany end table. After stripping the old finish, I washed it down with paint thinner then applied a coat of polyurethane. The finish did not take in some areas. I believe it’s called fisheye. I applied a second coat and it seem to fill in some of the spots but enough [...]
