I wrote a review about the vendor.  I doubt I'll know how well the product works, because the vendor sent me polish that seemed 20 years old: crumbling, dry, cracked, and brownish around the top.  Maybe the polish will still do the job.  But it's appalling to pay +$6.00 for a can of shoe polish that seems to date back to WWII.  If you buy this polish, I'd at least buy it from another source.
