To paint the INSIDE of a gas can?
The purpose is to discourage rust and flaking of current paint. I figure I can get a quart, pour it in the can, slosh it all about, then drain.
Else hire a team of hamsters with itty-bitty brushes.
Prior to painting, I plan to place rocks and sand in the can and shake it like mad as a substitute for sanding.
===== Because it's a military jerry can dated "Sep 1943" and has stenciled on it "III Army," which I assume was Patton's outfit. It will have a certain irony when used here with the Minutemen Project in South Texas.
