I have use this product twice now, on 2 different cars, and it has streaked severely. The paint is super smooth and slick feeling, but it’s agravating that I have to follow up with a wipe down of Sonax bsd. I have gotten streaks on all parts of the car. The worst seem to be the black plastic trim at the base of the doors. Those seem to “tiger stripe” the trim. All streaks seem to go away after another wipe down of Sonax brilliant shine detail. I have tried little amount of product, and this last time a medium to large amount of product, the rinsed throughly both times, still same results. I don’t think I will be getting a his product again. Am I doing something wrong? I have followed the directions.
