I've used this for many years on my Corbin. Based on beeswax, it conditions and seals the seams, keeping the wet out when riding in the rain...I treat the seat several times a year with it.

This seat is almost 20 years old and has almost 200,000 km riding on it...aside from one small separation at the seam on the Right side where the piping ends and where my leg has brushed over while mounting and dismounting over the years, it's still in fantastic shape. Still supple, with no cracking or fading at all.
