Pat’s tack on Rt 16 souith of Wales. They have Fiebings black latex leather dye. Mine weren’t that bad, but I did have some small white crack lines. I took the black dye on the corner of a paper towel and worked it into the lines. Using a liitle ‘touch’ I was able to blend it in pretty well. I’ve also been working the whole seat with Fiebings NeatsFoot Oil(not NeatsFoot Oil Compound). It softens it very well and cleans it too.
I think for both it was less than $15.
Note: My seats had a pebble finish and at first it was obscured by the dye. But as they dye shrank(a week or two) the pebble finish came back. My seats were ever so slightly a matt black and this has just a bit more gloss, but it still looks great and 1000% better than the wear spots.
