I was thinking of using some sort of Gummi Pflege
"1Z Einszett Rubber Care Stick “Gummi Pflege” conditions rubber weather seals on car doors, windows and trunks, protects and keeps the rubber elastic, restores color to dried out rubber, protects against extreme temperature and UV rays. Einszett’s solvent-free, water-based formula is packaged in an easy-to-use shoe polish-type applicator that makes application simple and neat."
Any thoughts?
