I would guess that about 98% of leathers on todays cars are of the coated type (actually all leathers are coated, if I remember correctly) which is a polyurethane.....again if I remember correctly
Leathermaster has top notch products and I've been using them for several years now. In fact I think I have the first post about the product on another forum all the way back to 2004!! Sheesh that makes me feel old
