Also, I like the little metal cans of paint because once opened, it can not be stored for later use.
X2 on POR-15, it will be the best fix for OP's problem. Wear some disposable gloves on your hands. *Anything* it gets on will be very hard to remove once dried. Lacquer thinner can clean up wet POR-15 paint. Once dry it is impervious to any solvent. So put some cardboard, drop cloths or similar under where you are painting. Brush it on, spraying is bad for your lungs. Throw brush away when done, so use the cheap brushes. Do not over-prep the surface, just wire brush loose rust off, it works best if not applied to clean metal, it needs some rusted surface for best adhesion. POR-15 is not UV stable, it will fade to flat after it goes on as gloss black if in a sun exposed area.
POR-15 is a moisture cured paint, so once the can is open, it starts to cure. That is the reason for the small cans being preferred. You can pour some out, then very diligently clean the can and lip before replacing the lid. That will save the paint, but if any paint is int he lip, it will effectively glue the lid on permanently once it dries. Some people put a layer of plastic film before the lid goes back down to help with removal.
