I've never seen this discussed before, but do any of the Megs products have a limited shelf life?
I'm not a professional detailer, just like to keep up my own cars. However, I would like to begin buying product in the gallon containers. The specific products I'm thinking about are m80, m83, and Hyper Dressing, but I'm interested in hearing about any other products as well.
Will these products go "bad" if I don't use them in a certain period? (probably a year or two for me)
