Can you show me the link to the product your talking about because the only one I know of is a waterbased product which is a cleaner made by Dulux/ PPG.
Thats defently not the stuff i'm thinking of. You don't happen to the know name of the stuff that you mix 50/50 with water and it goes white when when you do that's designed to clean also. I could have swarn that was called prep wash also but maybe it's a PPG product and not Dulux.:-?
