I am studying Bob Flexner's book. Lot's of great information and nice to see these products categorized according to chemistry rather than marketing.

I am really surprised how difficult it has been to find any of the products Scott recommended within 30 miles of my home.

I'll keep reading, then probably use mail-order unless they are not allowed to sell these high VOC products to people in Southern California. I firmly believe in taking steps to reduce the smog, and it does complicate the process as we develop new products.
