Classic cars feature numerous exterior rubber seals that are more exposed to weather, UV and detergents than modern daily transport. If seals aren’t maintained and protected, they can harden, shrink and crack prematurely. 303 Seal Protectant is a proven formula designed to condition rubber seals by restoring moisture and flexibility, helping to extend service life while maintaining a natural, original, non-greasy look and feel. Supplied with a handy applicator, apply after washing to windscreen, quarterlight, door, boot and hood seals
