Questions: Headlights and Seat Heights.

I can add that the oven cleaner works to remove anodizing, I've used "Easy Off," to do it. Though, i never tried it with the parts in an oven. Be prepared for noxious fumes either way. If I remember correctly, I had to use an abrasive pad with the oven cleaner to get the anodizing off (this was to remove colored anodizing from some BMX bike parts, decades ago), leaving just the raw aluminum color to polish.
