I am wondering that is the shelf life of the CarPro CQuartz after it has been opened. I was going to stat apply the product over several days because I do not have time to do my entire truck in one day any more. And I just want to make sure that it is not going to go bad over the course of a few days or a couple of weeks.

Thanks.
 
Once the bottle has been opened you will have maybe 6 months of shelf life left. Just make sure that you put the cap back on the bottle after using it. Keep the bottle away from moisture.
 
guess that means I have a half bottle of cquartz tbat is expired. dang it!

See if the product has gelled. I have a bottle of Classic that has been opened for over a year and is still good.

May I add, do not over tighten the cap as I have in the past. The cap being plastic will break before the glass bottle. It will develop a hair line crack that you will not notice.

it is still liquid. kept inside climate controlled room its entire life. and in the box even lol
 
C3 and C4 will keep idefinnetly if you do the following:

Seal the cap with masking tape.

Store inside in 65 to 72 F temperature.

Keep in dark space.

That is direct from the manufacturer.

Should be same for CQuartz
 
I usually keep older opened bottle to use on wheels. You don't want to take a chance of it crystallizing and causing scratches on paint, but they work perfectly fine on wheels.
