Some feedback from me:
I am still not that impressed by Swissvax Opaque Car Bath (Shampoo).
Although I use almost twice the recommended amount per volume of water, there is barely any foam and the solution feels marginally slippery...
That's not what I am used to from other shampoos for normal paint.
What is your experience?
I am thinking of trying a different brand shampoo. The rest of the Opaque series products are really great, it is just the shampoo I am not too impressed by...
