Hi Michael,

I know that you would not advocate a simple substution. I was answering Bob C's post which appearred to ask just that question. I also wanted to post D-76H as a remedy to the cost of hydroquinone. Since there is nothing to regenerate the metol as it is used up this version cannot be replenished. Looking back I was probably a bit rude to reply since Bob's question was addressed to you. My apologies.
