If the original hardware is in good shape I just get it Zinc coated clear. I tried yellow, but I like the clear better.
Bolts and nuts turn out like new. If the hardware is in bad shape I hit a hardware store or get a polished bolt
kit off eBay.
I also had the axle for my 250R zinc coated and it turned out excellent.

The yellow (Gold) doesn't turn out so well on my LT250s
