To be brief on some of my approach to repair, I do any metal repair needed to the plate(s) after blasting them clean of rust. I straighten out the edges and can also remove denting and even replace small/medium-sized pieces. Cracks and holes are repaired if present. The back of the plate(s) are refinished to new condition too. Surface prep is key for a smooth finish, any pitting present on the front of the plates will also be removed. The lettering is smooth, consistent and has an original look, no brush marks.
I do accept most state or country, metal embossed plates from 1903-1980. I have accurate information for correct colors on all states. Premium grade automotive paints carry out the job, not some cheap, rattle-can spray paint from your local hardware store.
