I still use some Swissvax products, but only on my show car. They are good, but - as you say - Bilt Hamber also provide excellent products which are great value. I’m a huge fan of their snow foam and wheel cleaner in particular, as well as the Hydra Wax (liquid).
It’s an interesting video. I’d never have my show car ceramic coated for two reasons - partly because I like to correct any minor imperfections easily, but mainly as it just doesn’t need it being for dry Summer use only. However, having now had my last two ‘everyday’ cars coated I can say the ease of maintenance makes it worthwhile in my opinion. By coincidence my new RX is being sorted, by the specialist I’ve used previously, tomorrow. I simply don’t have the time I used to have to keep the car in the condition I like, and a ceramic coating supports that choice.
