Some years ago, I was told by a professional wetsuit repairer how to safely store wetsuit contact cement so that it lasts for ages. For the following technique, I'm using Gear Aid Aquaseal + Neo Contact Cement, but whichever make you use, note how it's shown on the display rack in the store. In my case, the product was hung vertically, nozzle down
.
Open the pack such that the pack can be reused, but can still contain the cement.
After repairing the wetsuit, carefully remove any remaining cement from the nozzle and its threads.
Refit the nozzle cap.
Replace the tube of cement in the original package.
Place the package in the fridge, in the same position as it was in the store. In my case, it was nozzle down.
I placed the package in the "normal" part of the fridge, in the fridge door, at the top.
The cement just gets cold, but doesn't set.
To use the cement, take it out of the fridge and let it get to room temperature.
By keeping the cement in its original pack, the "kitchen owner" will not be tempted to use it on food being prepared.
I've just repaired a wetsuit using the cement I've had in the fridge for over 12 months. The nozzle cap unscrewed easily and the cement flowed easily. Worked perfectly.
.
Hope this helps.
or a front wing departure?
