I used to use Lexol and it seemed to work real well. But it only conditions the leather (couse the leather needs to stay conditioned)...the cracks and scuff marks from normal wear and tear are still there.

The Liquid Leather Scuff Master kit contains a water based dye that you wipe on then wipe off. The dye stays in the cracks. For spots where the colour has worn right off you dilute the dye and wipe/spray/brush on building up colour. What you end up with is leather that is not only contioned (comes with a quality conditioner) but is also renewed in areas that have lost their colour.

They also claim that the conditoner leave a smell of quality, connolly leather. (they claim that leather used to be tanned with a variety of substances including urine and that this product imparts that old world fragrance....???) It does have a unique smell that does remind me of walking into a quality leather store and not a men's room!!
