Mark...We're sharing a brain. I studied it last night after I read Marc's post. I think with a gradual approach using diluted bleach it would be ok. Maybe start 60/40 water to bleach mix and see how it responds.
The price was a little higher than I wanted to spend on an experiment. Thought of sending him a message to see if he'd take $50...but ultimately decided to pass. I think it would turn out great. Make friends with the guy and see if he'll come down some.
Let me know what you decide...I'm bored and want to experiment so I may take a flier if you don't. But I'm not a "baseball guy" per se....so rather it go to someone who is.
