    I would like to polish my eagle's feather tips to a mirror finish but leave the areas between feathers rough. How do I remove the grease from the sculpture without ruining the high gloss areas? Some sort of chemical?

    I've used alcohol and Acetone. Neither dissolves it but Acetone does a little better job of cutting it loose. I use a shop rag dipped in it and a fingernail to wipe it away.

    well DUH! prepsol wax and grease remover of course...;) LOL :D Its used by body shops to wipe down the cars before painting to make sure there is no grease or oil on them... Works great..

    Haha ok I'm try prepsol. That polishing compound gets thick in crevices. After the funk is removed I'll patina the low areas with liver of sulfur.

    LOL youll need a tooth brush also to get it scrubbed out of those tight areas.. Mineral spirits might work as well or bug and tar remover. I use the prep-sol because I can clear coat over it without worries.

    I use Laquer thinner , let the entire piece soak if you can, then give it just a touch of love with neverdull

    OK being Curious I did some Research on Prepsol and found it was over 50% Naphtha , most of the rest being Non Regulated it's probably Water

    I found these Naphtha products: at about 1/10 the price

    I reviewed the MSDS of
    Military Specification TT-N-95
    and it seems this s a More potent version of Prepsol, and much cheaper???

    I've used lacquer thinner as well, it does not penetrate as well and evaporates too fast. But is good for a secondary wipe down.

    Acetone.. Nothing water based or she'll turn green.

    In Florida, I can bead blast bronze and watch it turn green inside of an hr. Humidity is murder on clean bronze.

    Wish I could get mine to turn green that fast.
    I've had a piece sitting outside for 3 years now and it still has not...

    Something is wrong with your bronze. Is it some home made brew or actual everdur? The best way I end up with green is sweat on it. I'm going to bottle some stink juice and call it insta-green.

    Yep actual everdur, sure your not pouring everdull or something? Or maybe your pours are mostly dross and slag? (good reason to cover them with liver of sulfur) :p
