Hmm, then think I made a mistake ordering the Mini to match the P+, perhaps I could bead blast it myself. Would hate to ruin the engraving though. Oh well, looks like I'll have to order a polished mini now too.
Don't worry about it! It's really not that hard to refinish your own mods! The finish of SS is pretty easy to work with, so you could always polish your P+ using a bristled wheel and black compound to achieve the machined look, polish it using spiral sewn cotton wheels+red compound and then canton flannel wheels+white compound to achieve a mirrored finish, or search around locally or online to find a shop that will media blast the DID for you rather than doing it yourself. Though if you do want to make a project out of it, I'm pretty sure there are some really inexpensive media blasting boxes out there that will definitely do the trick.
And on that note, I just polished my P+18650, but I taped off the ends so only the middle section would be polished. I'm not sure how I feel about it just yet, but after I polish a few more little things on it (the lock on the switch for instance, but i need to use my dremel to do that part, it's too small for my 6" wheels, it'd fly right out of my hands), I think it'll look a little bit better. This was really just an experiment to see if taped off areas would hold under the heat and friction created by the wheels and still produce clean cut lines, which it did! More experimenting to come! For now, here are some pictures of the final product:



And here it is all taped up. Disregard those gnarly smudges and swirl marks, after a good rub down with 3 gradients of microfiber cloths and some swirl mark removing powder, it's as polished as can be

Another word on (or off) the street is that it's dropping soon...
