  • Sill plate restoration

    Could use a little help. And yes, I have searched this site on cleaners, stainless restoration and other options. I would like to re-furbish my original sill plates on my 50 stude four door. I've tried acetone, metal wire buffer wheel, soap and water, etc,etc...and can't afford $239.00 for a new pair from Studebaker Int.($478 on mine). Any help for today's project would be greatly appreciated.
    Thank you

    I believe they are aluminum. Probably the best you will do is to start with 00 steel wool, then 0000 steel wool, then a good aluminum compound and polish.

      I think just a good metal cleaner and then a metal polish like Mothers chrome polish or similar. High polishing will show flaws, so be careful. Nothing is going to make 63 year old aluminum look new after all those years of skuffing and corrosion from the elements. You could also contact a powder coater to see if the plates could be freshened up to look good that way. If you're just looking for something to look nice, you can buy stainless steel in different widths and thicknesses, cut, bend and drill to fit.

        i've used "Mothers Mag and Aluminum Polish" on several vehicles, including the 40's sill plates. also used the "Mothers Power Ball" and a "Dremel" polisher on small parts to remove the polish.
