Polish it and you will void your finish warranty with Taurus. You may also ruin any resale value it has, at least in my eyes!

There are certain guns that can be appreciated when they are nicely polished, simply because they came that way from the Factory! Older Colts, Lugers, Walthers, S&W's, Older Mauser and Winchester Sporters, and others, nicely polished, will be collectable and appreciate. The 24/7 is not one of them! The 24/7 is a modern matte finished Combat Pistol and that is what the market expects it to be! The Market determines pretty much what is valuable and what isn't! Another downside is that a polished finish won't hold protectant as well as a matte satin finish will.
Don't come cryin, if and when, you decide to trade that polished 24/7 in for something else and the GunShop will only give you a pittance for it! I won't be hearing it!
As kashdaddy has pointed out, It's your gun and you can customize it as you wish, but you've been warned as to the pitfalls of doing so!

As for a protectant oil, the S&W Lubricant and Protectant should work very well as a protectant. Hoppes Gun Oil is only repackaged Mineral Oil, and should serve very well as a Lubricant, but there are also other Oils that serve well. I would use the Hoppes #9 in your kit to clean your Pistol.
