Wow Mark that kit is beautiful!So no Novus huh?are there any cleaners out there that are good for SF finishes?
Yes, it was a beauty! Correct, no Novus for SF finishes. And, I'm not aware of any commercially available cleaners for SF. You've probably felt the textured surface, right? It's that texturing that can hold and trap dust, dirt, grime, etc. Careful cleaning with a mild dish soap, such as Dawn, is all you need. You don't need much! You'll also need that soft bristled toothbrush to get out any tough grime. Once clean, you can keep it that way with a micro-fiber towel.
To answer the previous question, there's not much you can do to keep the wrap from cracking. If it has yet cracked around the lugs, just be sure the lug screws are not too tight. It's the pressure of any hardware against the wrap that causes it to crack.
