Weather Proofer
Weather proofer is a coating put on soft top roofs to help protect them against moisture, oxidation and mould.
This is sometimes called water proofing, however, while the coating repels water, it doesn't make the roof waterproof, it is the membrane and rubbers that keep the water out of the car.
Making the fabric repel water just means that it stays dry. You can tell when the weatherproofing has worn off of your car because after it rains, your hood will be soggy. A wet hood is an invitation to mould, fungus, algae and lichen to grow.
Most weather proofers will contain a mould inhibitor to help prevent this, and because they coat your fabric, also act as a sacrificial layer which prevents UV light causing oxidation.
