How do I go about painting a picture over a rusted patina milk can?
I have the last milk can from my grandfather’s farm, from before 1950, which contains only surface rust. I know I need to clean it up some but I want to keep the rusted patina appearance though. What kind of Rust-Oleum type spray paint is needed to seal it while at the same time giving the can a low gloss finish for the first part of my project with this treasure?
After this stage is completed I want a picture of my grandfather’s barn painted on the side of the can to finish the can. I’m including this bit of information because I need to know also whether the non-rust clear paint used initially will accept either or acrylic or oil artist paint?
Also so please tell me if I should just use a wire brush on the surface rust to keep the underlying rust patina or should I use naval jelly? I read naval jelly will remove all the rust taking the can down to the original galvanized condition. Is this true?
After the barn portrait is done the milk can will be kept in our entry on a ceramic floor. Will the existing rust make a mark on the floor or how do I prevent a rust mark from occurring? Thank you all for any advice provided.
By the way, the initial “J” visible to the right of the handle stood for my grandfather’s name. Since he started farming when horse drawn wagons came to pick up the milk the only way the driver knew which cans belonged to which farmer the farmer painted his initial on the can. Thought you might enjoy a little history lesson.
