A little WD40 or any silicone spray on the rubber seals of the ammo cans, helps keep them from cracking or drying out. I have also used a little petroleum jelly (Vaseline) on them too.
I sand off any rust and re-paint them inside and out. These cans should last for years and years. It is easy to bring a can of WD40 and a can of spray paint on your yearly cache maintenance run.
