refreshs and keeps rubber seals pliable and in factory-new condition for years

Let's get it right to the point: Rubber has nothing to do with plastics. Quite contrary, rubber is a natural product and most plastic care products have no business being applied on rubber parts (for plastic care we recommend you to use Swissvax Protecton or Nano Express).
Rubber tends to get brittle, cracked and unsightly over the years and unfortunately the replacement of all rubber seals on an automobile is very costly and for many older cars these seals even aren't available any longer. Therefore, regular care of all rubber parts is very important to keep your automobile in "factory-new" condition for a very long time. Seal Feed was developed exclusively for rubber and keeps rubber seals pliable and fresh for years. Additionally, it also effectively prevents seals from freezing in winter.
Hardened, cracked and discolored seals that have been neglected for decades cannot be returned to an as new condition. However, repeated application of Seal Feed will drastically improve their condition.
