My early '26 roadster came with what I believe to be zinc door sill plates. They have some minor damage. I would like to repair what is missing on one of them and fix the crack on the other. Can this be done? Also, what is the best way to restore these sill plates? Glass bead sandblasting or would another method be better?

here are the images

Can't help on welding cracks in zinc, as fumes from zinc are very dangerous to your health.

On mine, just left the few bumps and cracks as 'patina'. The repro parts in aluminum don't look good to me at all. So keep your originals original.

Just buffed the surfaces of the plates on the buffing wheel, then a coat of wax, provided a nice sheen that was likely what they looked like when new.


Touring rear plate, before polishing on buffing wheel. Think that vapor or sand blast finish wouldn't be like the shiny original type finish.
