Here are a few best practices to ensure your adhesive will perform when you need it.
1) Store your adhesive in a vertical position so that air will rise to the top and it can be bled out
2) Leave the tip on or put the original cartridge nipple back on to reduce the changes of getting a plugged opening
3) Store your adhesive in a cool or room temperature environment
4) Use your oldest adhesives first
5) Check the date on your adhesives. Adhesives are warranted for 1 year and are generally good up to 2 years. Always test adhesives first that are getting close to their end of life.
6) Do not leave adhesives on the dash of your install vehicle. The excessive heat will impact the performance of the adhesive.
