Hard and soft

Q: I am building a modern looking pine dining table using lodgepole pine. The wood is extremely soft and dents easily. Is there a product that I can use to harden the tabletop so it minimizes dents. A: Yes, in theory, though it is not generally deemed too practical. There are rotted wood repair kits [...]

In the buff

Wednesday, April 28th, 2010

Q: Can I buff waterbased acrylic and be able to get a fair shine? A: Certainly, assuming you started with gloss acrylic. However, it will be much easier, and you’ll get a much better shine, if you wait until the finish is not just dry, but cured. Waterbased finishes generally take about a month to [...]

Fisheye barrier?

Tuesday, April 27th, 2010

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?

Not so deftly finished

Monday, April 26th, 2010

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 [...]

Safe blocks

Friday, April 23rd, 2010

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 [...]

Young Chang guitar

Thursday, April 22nd, 2010

Q: I bought a Young Chang acoustic guitar in 1981. It resembled a Martin. Was this guitar a creation of yours? Do you know anything about it? A: No and yes, in that order. I did not start working for Young Chang until 1995, after I left Martin. As for the resemblance, that’s pretty easy [...]

Osage, oh fade

Wednesday, April 21st, 2010

Q: I’m using Osage Orange for a sunburst top, and discovered it tends to color shift to brown. Is there a finish or other method you know of to prevent this? A: Many exterior coatings, both oil based and waterbased, contain UV absorbers or blockers. These help, but to be honest, they really only delay [...]

Wax won’t abrade

Tuesday, April 20th, 2010

Q: I have a can of Butchers Bowling Alley clear paste. Is this the same as automotive compound? A: Nope, not even close. It is wax. You stopped short of the entire name of the product; Butcher’s Bowling Alley clear paste wax. As its name suggests, it is pure paste wax, which is a combination [...]

Scratches, away!

Monday, April 19th, 2010

Q: Our regularly used dining table was refinished in dark brown, high gloss lacquer and shows superficial surface scratches with use. Is this is normal? A: It is for lacquer, which has only moderate scratch resistance. To make things worse, scratches show more readily on gloss surfaces. Lacquer does have good stain resistance, but not [...]
