Seriously though - I have worked with Glidden/ICI products for years - I know them very, very well. I know which works where, why, and how.
I am not so blinded as to think others in the world don't make a good product - SW, BM, PPG - the local grinders - all have good and bad products - just like Glidden.
I want to recommend to people what I know works - and I know Glidden best - and it works!
