Hello to ALL yoy creative people!! I need your suggestions...Please!! I purchased about 30 or more of thes old vintage bread and picnic boxes. I would like to clean them up, stop the rust, before I resell.
Cant really paint them as they are all different, but would like to make them usable. Food safe.
Do you think that is possible?
Would love to hear your suggestions!! My living room is covered in tin boxes! LOL!!
Thank you in advance!!! I appreciate all of you!
