Is
Meguiars the best..
For Bricks and Mortar stores, hands down the best in my opinion.
Their consumer line should be looked at by management and a lot ofproducts removed off the shelf. Too many similar products and some just don't need to be there.
Their Pro line is EXCELLENT. Almost faultless but again, there's probably a few products in there that can be discontinued as well.
Their Detailer line is Amazing as well. If anything, this is one of the lines should be trying to get into mass more i.e. Glass Cleaner, APC, Degreaser etc.
Then there is the whole question as to why does one company need 7+ shampoos???? Seriously..
That being said, when you look at online competition and products typically only available via online shipping. Things change up a bit.
Then it becomes more of a 5-10 race and really, none of them are better then the other but more a personal perference.
Meguiars,
Menzerna, Optimum, Zaino, Poorboys etc.
So taking that into consideration. Yes they are the best overall company in the US and Canada, by quite a margin. They could even strength that position if they made their consumer and pro line less complicated.
