    It's time to retire my 20+ year old BFG tires. So, I'm planning on refinishing my N90's before I swap tires. I've read several posts by Twisted Metal and others on the topic. I'm looking for a sanity check so I don't do something stupid.

    My plan is to use a fine aggregate in my sand blaster and blast the old finish off the rims. I have a lot of tar and baked-on crud on the inside (back) of the rims as well. Then, I'm hoping to polish the machined surfaces, and then paint / clear coat the originally painted surfaces (after masking the machined surfaces off).

    My concern is over blasting the machined surfaces. Will this do more damage than good?

    You will lose the orginal lathe marks on the turned edges when you blast them.
    The ridges got cut off when I did mine with by hand with steel wool.
    Those tiny ridges are quite delicate.

    Soda blasting will remove the original powder coat finish and preserve the machined surface but it's a slower process than a fine abrasive media.

    Unless it's on a lift, you never see the inside portion of these wheels.
    A chemical cleaner (solvent) would be better for cleaning tar etc. from the inside.

    If you want them to look perfect for a long time... A professional restoration with powdercoating is the way to go.

    I only did two of them by hand and got tired of the process. :screwup:

    (I still have 14" N90s on the front so I only refinished two of the 15" ones I have. I keep telling myself... some day I'll have all four professionally restored and go with 15s all around.)

    A lot depends on your expectations.
    Doing them by hand is a lot of work and they can turn out very nice looking but the machined edges won't have that factory freshy cut and sheen to them.

    Can I see a picture of a N90 ? I'm not too familiar with their name? I'm sure I have seen them...

    I would be happy if my N90's turned out like yours, Twisted.

    I read the above links again, and I think I may give walnut shells a try in an inconspicuous area. I don't mind if I lose some of the lathe marks. I just want the rims clean, polished, and fresh. Right now, they look like 30+ years of nastiness.

    It's all your fault :crazy:

    Perhaps this is also a good time to install the link lock that is sitting on my workbench - just for one final goodbye to the BFG's. [​IMG]
