For about 5-6 years we have regularly been using the program "Antigilb" (still under the crane in autumn), "Rubbing", "Polish" and "HardWachs". It's a bit of a hassle and rubbing, polishing and waxing makes you want to go, but you can look forward to success throughout the season and especially in autumn when the weather and the waves have left almost no traces. Surely there are other programs that work, but it works and that's why we stick with it.
