Experiences with Sonax Polish&Wax 2 Nano Pro??

Hello together, has someone here gained experience with Polish&Wax 2 Nano Pro?? I know that the Sonax products have not called the best for the “care professionals”. But I had the stuff “unfortunately” turned on by an ATU seller and only later in various forums read that you can forget the Sonax products if you expect a useful result! My question: Can I still use the product in between times or should I put it in the corner and take another product and if yes which one for my lacquer condition (except for a 6 cm shramm fender, about 4 cm shramm bonnet both up to prime so don’t think polishable and few 3-4 stone strokes naturally quite ok)? see picture….
