Actually, that was my processSignatureSeriesOwner wrote:Tim Gracyk's process seems to be an OK one to try, but wouldn't 600 grit still "scratch" the overall surface? In other words, even when you stop sanding, you'll still see a crap-ton of little mini scratches all over the thing, wouldn't you? Rottenstone is mentioned, but the only place I can easily find online that has it is in the UK, and I've never used it before. Would it remove the fine scratches and leave a (relatively) reflective surface?

#600 wet or dry (3M) sandpaper is extremely fine. It almost feels smooth to the touch. It DOES have to be used with an oil based lubricant, though. But, if you're concerned, you can test it on an inconspicous area fist. You can also get even finer sandpaper at most well stocked auto repair shops, such as #900.
As for Rotten stone, I believe you can still get it from ASPCO -- http://www.antiquephono.com/cabinet.htm -- at least it's still listed on the page. This place also sells it -- http://www.rockler.com/product.cfm?page=2184
