After cleaning out the garage, I came across some old products, like Meguiars quik wax, Rain-x wax, and other products along the lines....They are all at least 3 years old, and some may be as much as ten years old.
Do you think that they are safe to use on my paint?
Or should I just chuck them and buy new?

 

I would chuck them, with the cost of new products OTC being so competative, I wouldn't risk running into problems with them and would just go buy new if I needed something..
