Hey guys, John Allison of Envirospec is "old school".
I have NOTHING but respect for John.
The man knows his stuff.
I can't imagine it being no good.
The ONLY reason I asked what is in it was so I could make a suggestion of HOW much is needed.
There is NO "perfect" roof additive.'
There are different schoools of thought as to what is best.
Simple Cherry has it;s place, it smells goood, and no worries about it hurting stuff.
Powerhouse is some wicked good stuff, maybe best for really dirty stuff.
Apple Sauce is good, but has solubility problems, and Apple Cider burns up the Mix IF left too long.
Lets see what John Allison has come up with, and how much it costs ?
