I am a new user of PPG products and so far the results using Redman's and Jeremy's tutorials have been excellent....just getting ready to sand and buff the clear coat.....but I have lots of DCX 61 left in the 8 oz can.....

I know it's been posted before, but I can't find the specific thread.....what is the concensus regarding shelf life of PPG DCX 61 hardener......the can says use in 2 weeks after opening......any problems using it after that date.....can it be stored in an airtight container at room temperature or should it be cooled in a fridge like aeropoxy.....

Thanks for any help....

Tom
