Just did the polished tunnel last weekend on my APEX. I went to Menards looking for Mothers, they didn't have it. I have a tube of Ma's up north, forgot to bring it home. Bought this turtle wax wheel polish, it worked O.K., but nothing like the Ma's. I also used what was left of a tube of Flitz and that seemed to work better than the Turtle wax product, but still not quite as well as Mothers. Long dirty job either way, but the degree of polish/shine is directly proportionate to the amount of time you want to keep going over tarnished spots. Long story short....Mothers is best, Flitz is a relatively close 2nd.
