Reply to "Cheap way to "polish" your ZF"

Back on the subject of cheaply spiffing up the ZF, in chassis, what do you think about a cheap little experiment:

Fire up the compressor and attach the hand held sandblaster that has the hopper fixed on top. Load the hopper up with cornstarch or talcum powder and shoot the ZF again. Cornstarch and talcum powder are smooth as a baby's behind, and maybe that's the next step to a "polished" ZF.

What do you think? Is it worth it to try it? It'll be a major mess to clean up, but how many times did Edison try before he perfected the light bulb. Anybody tried this?

Actually, it's pretty spiffy looking now, but not mirror smooth. I'm going to pull the ZF next year to install the taller fifth gear, and the cost of polishing is under a grand, so I'll do it then, the right way. But I want to put it in a car show or two, at the local charity events here, and that's my cheap-out way to get to the interim goal of the 'in-situ' polished ZF. Have a little fun.

Anyone have an opinion whether I do this in the driveway and send a cloud over the neighborhood or close the garage and do it inside and deal with the mess. We're not talking toxicity here, just manners. Wait for a windy day? Rain on the horizon? Or let it rip and tell them to bring the car by for a wash if it bugs them?
