Sorry i forgot to mention all the paper in my fridge is fibre..with only one box of kodak RC.

The other day one of my friends gave me 25 years old Agfa paper that was stored on a shelf in the garage and it worked flawlessly.

A common sense is "If you can survice, so can your film" So aslong as its normal conditions.. you will be fine...

and no the trunk of your car in a texas summer is not normal...

have fun
