303 Rubber Seal Protectant

by 303

We Say

The rubber seals around doors, windows and other panel openings serve an important function; they keep unwanted air and moisture out. However, as rubber ages it tends to dry out and harden, which often results in seals failing. Furthermore, this weathering also makes doors and windows prone to freezing shut during the winter months. 303 Rubber Seal Protectant helps to prevent these issues, as it restores and maintains the suppleness of rubber seals, enabling them to continue functioning like new. Its powerful conditioning action also restores the natural colour of seals if they have already faded. 303 Rubber Seal Protectant is very easy to apply, dries fully to the touch and does exactly what it promises to do. We love it!

303 Rubber Seal Protectant is a water-based conditioner for rubber seals. If rubber seals aren't maintained they tend to dry out and stiffen up over time. Furthermore, if they are continually exposed to sunlight, they can fade and become brittle too. When such degradation occurs the seals will no longer work properly, allowing moisture into your car. 303 Rubber Seal Protectant guards against this by blocking out harmful UV rays and restoring the softness and elasticity of rubber seals, along with their natural colour if they have already faded. When used regularly, 303 Rubber Seal Protectant keeps rubber seals looking and performing like new, and its built-in applicator makes it extremely quick and easy to apply.

How To Use

303 Rubber Seal Protectant should only be applied to seals that are clean and dry. In many cases a wipe down with a damp PB Utility Towel will do the job perfectly, but if the seals are more heavily soiled then a multi-surface cleaner may be required. For best results, shake the bottle vigorously and then wipe the product on thinly and evenly using the built-in sponge applicator (press it down and squeeze the bottle gently to get the product flowing through the sponge). Allow the product to soak in and dry for several minutes, and then buff off any excess using a dry PB Utility Towel. If necessary, repeat the process until the desired results are achieved. Thereafter, reapply it every six weeks for optimal protection.
