Been learning to fix dings the last few months. Super fun, except for dealing with the caps on my resin tins. Always wrestling to get them off; I have to use pliers. Eventually the caps get too dented, and I can't use them anymore.
Anybody know any tricks to prevent this? I've tried wiping down the threads and the inside of the cap with acetone, but it doesn't seem to work.
Better yet, maybe I should just transfer everything to a different container? Any air-tight and UV-preventing plastic would be good, right?
