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: I am making blocks for my granddaughter and plan to use Ceramcoat acrylic craft paint to give them some color, but can not find out if the paint is child safe. The MSDS does not address the paint once it is dry.
A: Actually, it does. Section three of the MSDS says, and I quote, [...]
Q: Here in my country there is only one kind of gold size; a waterbased size which is white in the can and cures colorless and gloss. We have to thin it with water and apply it with a little cotton ball. This process of applying the size takes a lot of time and sometimes [...]

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 [...]
Q: I have been using Minwax Satin Oil Based Wipe-On polyurethane for finishing my kitchen cabinets. I can’t buy it anymore in California due to VOC laws. Is the water based product going to give me the same results?
A: Depending on your criteria, you may or may not find it acceptable. It is developing a [...]
Q: I find conflicting information as to whether polyurethane can be rubbed.
A: Any finish, including polyurethane, can be rubbed provided it is sufficiently cured. As a rule, the longer the finish cures, the harder it gets and the easier it is to rub. Attempting to rub out a finish that is still rubbery is an [...]
Q: Can I put one coat of oil based polyurethane on some drawers, wait eight hours or so, and then overcoat the oil based polyurethane with several topcoats of waterbased polyurethane?
A: Sometimes. That is to say, some waterbased polyurethanes will adhere to some oil based polyurethanes, but not all will do so. I’d let the [...]
Q: Where can I get information on custom color stain? We can’t find the color we want for an entertainment center. Can you teach us how to mix our own?
