I understand that CFP produces formaldehyde-free plywood for decorative interior applications. Do you have any recommendations for a formaldehyde-free product for subfloors? Is the phenolic exterior plywood the best bet for limiting indoor formaldehyde emissions from subfloors?

Subfloor panels on the market today are most often produced with a phenolic formaldehyde adhesive. While the glue formulation does utilize formaldehyde, the cured bond releases so little that it is considered safe by the regulatory agencies. It is not technically formaldehyde free, but any amount emitted would be indistinguishable from background levels of formaldehyde present in any environment.

I need a close match for McCloskey Tungseal stain - Light Oak 1917.

The McCloskey brand name was purchased by Cabot coatings about 5 years and the Tungseal line of stains discontinued. There is no replacement for the Tungseal Light Oak. You will have to try on your own to find a Varathane brand or Minwax brand that matches your requirements.

If all fails and you have a bit of the stain left, try a Sherwin Williams Branch location that is listed in your yellow pages or phone book as a "Commercial Branch". They may be able to use their computer and experience in color matching to mix you up a replacement color in their wiping stain base. It's better to deal with the commercial branches if possible, particularly if you are a contractor or small business in the trades.
