>>6855661I've decided to do a little test: I've got two vials filled with Mr. Color paint thinned with hardware store lacquer thinner down to 2:1 and one full of just thinner and a couple of cheapo bearings I grabbed earlier. I'm going to leave one paint vial stored upright but shake it daily and store the other upside down so the paint is in constant contact with the seal to really stress it. I'll watch all of those and the lacquer bottle and check back in occasionally to let you know if they've shat the bed.
