Separation has always been an issue with this product, but people seem to generally accept it. Because of the special polymers used in this formulation, this product is very thin to begin with, much thinner than most products.
The strong polymers which make it work so good, wipe off so easily and last so long, are what cause the separation (it's not water, we don't add any water or other useless fillers in any of our products).
This is super weird, but if not used very often, we found keeping it in the refrigerator works great to help prevent the separation. The product will work the same and the other added benefit is it makes it easy to grab a cold one when you're ready to work on your car :)
The best way to get it back to normal is simply by holding it upside down while shaking.
After shaking, the product will work just as good as before. But if it's not what you expected, all our products are backed with a Zero Risk 100% Satisfaction Guarantee policy.
