  • Conditions all weather seals around doors, hood and trunk
  • Temperature resistant for long-lasting protection

For rubber seals in car doors, windows, and boots, Gummi Pflege offers long-lasting freezing protection. It also offers true, deep-down safety conditions, helping to extend the life of rubber seals, gaskets, and trims, offering protection from the sun’s cold, heat, and UV radiation.

If rubber seals around windows and doors go untreated they will deteriorate over time. As a result of changing temperatures and high UV sunlight exposure, the rubber starts to dry out, crack or shrink. When this happens the integrity of the seal will fail and lead to further problems such as squeaks, whistles, draughts, and leaks. The original luster is lost and the rubber continues to perish.

Unlike many plastic and rubber treatments, Gummi Pflege doesn’t simply buff rubber to look new. Gummi Pflege provides real, deep down protection, helping to prolong the life of rubber seals, gaskets, and trims, providing protection against cold, heat, and UV radiation from the sun.

7) Change Your Engine Oil and Filter before you Winterize Your Porsche Boxster

10) Set Tire Pressure

The most common problem encountered when winterizing and storing a car is that flat spots occur on the tires. Tires go flat on one side for carrying the weight of the car for an extended period.

To avoid flattened tires, overinflate all tires by approximately 8-10 psi. 
Overinflate the tires when the tires are cold, therefore you won’t get an inaccurate reading. Don’t worry about using jack stands or lifting the car.

11) Gas

Ensure your gas tank is full of premium fuel to prevent condensation and reduce tank airspace.

  2. Well, Porsche is a luxury car representing the German automotive industry. That does not mean, you will take its winter aftercare steps for granted. Obviously not. Like other automobiles, it is an automobile. So, keeping it winterized all along the Jack Frost is a must. You have to follow the same procedure for the winterization of Porsche. You need to check windshield wipers, antifreeze, battery, tires, brakes, and other electrical stuffs to winter-proof your speedster. Hiring a car-geek will come advantageous during the execution of the maintenance commotions.
