The more work you put into them or any wheel for that matter the better they will look. I personally would recomend considering Zoop-sealing wheeling prior to install and you still need to maintain but alot better and easier IMHO There stuff is big with Bikers and truck guys not as well know in car circles yet but starting to be. Check out there web site.
You can also clear wheel with mixed results some love it some not so much.
I use mothers Billet alluminum polish. It's not very agressive but polishes to a mirror. The absolute best thing about it is that it comes off five times easier than other wheel polishes. That alone makes it worth the extra money to me.
