Life of the products you use?

It's been said that older products can go bad or if you leave them in your garage that isn't heated in colder areas they can go bad due to climate change.

I've never thought much about this until last summer i did notice it took more product to do what i wanted to do but it could be in my head. i have a few boxes full of expensive products that i've left in the garage during cold temperature months for years without thinking.

is this just company hype getting us to buy new products every year? share your opinions on this!

I always move my supplies from the garage to the house when the detailing season is over. If stuff freezes up over the winter it's usually ruined come spring.
