For what it's worth, I've used AG house brands - started with them back 7-8 years ago. I wasn't saying there aren't differences in "some" products - I was commenting on common items like QD's, Cleaners, some polishes - all the same with different labels. Once, I got some free samples of leather cleaners - from 2 different house brands, you could NOT tell the difference.
Want more old boy? - the former guv-ment motors:
Chevy Nova = Pontiac Ventura = Buick Apollo = Olds Omega
same crap, different badges, I know, I had a few and I spent a couple years of my youth sanding cars at a body shop.
Does anyone think these brands are all made by different factories? No, they aren't, they're made to spec in 1 factory, same as many other companies do and are re-labeled and sold. Nothing wrong with that and I never said nor tried to imply that there was.
