If your high end saddle is getting a little tatty but the rails are straight, you might consider using Sugru to tidy it up before finally being retired to the pub bike.
Step 1: Rough Around the Edges?
The nose, sides and tail of a saddle are often subject to more abuse than the rest of it.
Step 2: Apply Sugru
Take a small amount of Sugru, roll it in your fingers to warm it up and make it more malleable. Apply to areas in need of repair.
Step 3: Tidy Up
Be patient, gently work away at it to get a tidy finish. Sugru is awesome stuff but if your fingerprints are left on it before setting they will be there for all eternity.
Step 4: Leave to Set
Leave the Sugru to set for 24 hours, then you're good to go.
