Interesting how many clears Rusto has. "Zippy" and I have have had several PM discussions about my use of the Rusto automotive crystal clear. It's my go to but I have never wetsanded it. It usually lays on so smooth just a good compounding, polishing and waxing has been good enough for me. BTW, I now use Createx acrylic and it works just fine on it. But for those who will be using it as Dave said, it will run if you are not careful.
