does anybody know whether gasoline will attack the plastic in a typical one-gallon antifreeze container?

Well, it's been two and a half weeks now, and the antifreeze container (a hard, white plastic bottle sold by NAPA auto parts) shows absolutely no signs of deterioration. The lid actually seals more securely than a conventional polyethylene (or whatever kind of plastic) genuine gasoline container, because the complex construction of those containers (in order to accommodate the extensible pouring tube and the vent opening) necessitates a lot more potentially leakable joints and seals.
