Q: I doubt that Zinsser® SealCoat™, which you mentioned in a previous answer, is available in New Zealand. Can you describe the characteristics of this product so that I can find a locally available substitute?
Michael Dresdner: It’s dewaxed shellac dissolved in alcohol in a convenient to use concentration. For the record, Zinsser does have distribution in New Zealand. Go to this page and scroll down to the second entry from the bottom for all the NZ contact information.
