I used Swizvax (in German speaking countries known as Swizöl) products for the last 5 years on my MGB and will definitely do on my P5B Coupé too in the future. I once bought the discovery kit and used it once a year and have still a leftover for another 5 years. Swizvax is is just amazing not only for the results but also for it´s handling. The wax can be applied with bare hands which is a true sensual experience. The beginners set also provides different cleaners and tyre conditioner.
