    I like to keep mine fresh..

    I have had good luck tumbling balls, but it did take a while for my first batches. I am not sure if I found a magic balance in my media or what, but I seem to be able to do them in ~ a day of tumbling now, though I have not done it in a while.

    Also, if you are starting with beater balls expect it to take seemingly forever, some are just too far gone.

    Bottom line is in my experience you can bring most balls back to a mirror finish in ~2-3 days of tumbling, anything more than that I just put them in my too far gone pile.

    I do have one that when tumbled up turned into a disco ball... I think it was in the Paragon I had bought where the shooter tip was missing and the metal had fully mushroomed on the tip of the shooter rod.

    Quoted from Fanatic:

    What polishing medium did you wind up using?
    I wonder if more steps are required with coarser/finer media.

    I used walnut media. Lizard bedding from Petsmart. Don't know the name offhand. As an additive I used Kit's Scratch Out as recommended by John Wart Jr.

    Maybe the balls were too far gone as said, but I was hoping to see better results. They really don't look much different at all. I'm not ready to tear down my Firepower yet to tumble some other parts but I'm sure they'll tumble better since those parts are mostly dirty than scratched up from rolling around and banging on everything.

    Ipad camera sucks. But here's what I used.

    Is walnut harder than corncob media?
    Regardless; It may take some trial and error.

    yes there are more steps first corse media to smooth ot the rough stuff the a polising media to mirror it and then I would use the shell media. with a polish liquid additive on the second step.

    My brother in law bought me some for Christmas. I thought it was a gag gift...like super glue or something! But it's the real deal. My balls stay fresh and dry all day. Tiki should use this sh*t...he probably wouldn't post no much nonsense if he was more comfortable.

    I would just get new "plain" pinballs and polish the new pinballs. You can get them for under $1 from pinball life if you buy more than 50 at a time. That's what I do.

    Hmm, those pics are not good. I have had much better success using walnut media with Novus 3 in my tumbler. Maybe try that combination.

    I put the balls on top of the media, spread the Novus over the top half of each ball and then maybe 3 big loops of novus around the middle of the tumble, let it tumble for 72 hours, and they generally look great.

    I also tumble new balls to put a mirror finish on them before using them, so that works too.

    Whenever I examine old pinballs it looks like the finish has chipped off in places so I simply opt for a new set. By the time you pay for electricity, media, and additive in a tumbler I don't think it's normally worth tumbling them. For all other metal parts, it is. I've had parts come out of a tumbler or hand polishing that look better than replacements I've ordered.
