Shelf Life of My Bottle of CQuartzUK Expired?

[dguber]

With the specs listed on the label in the pic,

Can I still use CQuartzUK if applied in the next few days?

Will I still get the same durability even if the EXP is about to expire?

Also, the bottle has only been opened once one time last year and stored in a cool, dry environment all winter long.

Thanks

Once the bottle is open the EXP date goes out. You basically have up to 6 months once it has been open, because the product has now made contact with O2 in air

If its still liquid , not as gelly kind it will be fine,
but check it well first

I agree whole heartedly with the good doctor for sure!!! 6 months after being opened and exposed to air is the max limit for me (and then it would only be used on one of my personal vehicles, NOT a customers)! I have tested this more than once, and after 6 months of being opened the durability is GREATLY diminished! To me it's not worth taking a chance (again). I certainly don’t want to have to redo all the hard work of prepping a vehicle and coating it again in 6 months or so just because I used old product.
