I'd just like to add the only reason I use OPT products was because of A&J and Lowejackson and the posts they made on a UK based detailing forum. As mentioned in my introduction due to health issues the whole snow foaming, rinsing, 2 bucket method, etc. was not an option so without them and their posts I would probably have a very dirty car and also miss out on the quiet time I get when I get to clean my car (which is usually needed!).
They are both a real asset to your brand.
