Well many thanks for your kind comments guys, it gives me something to go forward with.
Its always good to know I have lot of backing 
easiest way to generate business = speculate.
give out some free samples to window cleaners = your target audience , to trial them for you.
the unbiased opinions you will receive are a great form of advertising your product on here.if its any good that is.
not knocking you by the way, in fact im trying to help you with your product.
if its pants then its ebay for you , hoping for the penny pinchers is how it will go ( i hope not by the way , i love innovators, speculators)
as i said im currently trialling a product from a big chemical manufacturer with full MSDS sheets and would love to see how magico compares.
it may blow it straight out the window, again it may not.
