Hello, now have the FAQ and countless articles through and there are still a lot of questions for me. At the moment I am thinking about which foam powder / foamer I should buy and which means I should fill them – besides water of course -. Since I am absolute beginner and initially investment costs are high, I would like to note that the price of course plays a role. Nevertheless, I want to avoid long-term planning and especially expensive beginner mistakes. Among the ones that have reached my narrow selection are the beginning and after some articles, blogs and videos I thought to myself the Gloria FM10 is sufficient and a good choice. In the meantime I am unfortunately not so sure anymore. Background is that I came across this e.g. and my SUV (BMW X4 F26 is not exactly a compact car now. What do you think is the better choice and why are you this opinion? With these I know even less and have the In my narrower selection, the time is quite basic: Do both products have the same purpose, namely to produce a beautiful foam or are these two products, which have a different range of application and if so, which one? So shampoo I have bought the Sonax Autoshampoo Concentrate 2l (in red color) for now. For better or other alternatives I am open at any rate. Which mixing ratio should I then use with this product? or use your alternative per litre.
