Dynax Waxoyl

Hi all

I am getting all the stuff ready for rust protecting the 210 and the new 209.

I am going to be getting Bilt Hamber Dynax stuf. It seem as though Dynax UB is thicker and for under the car, and Dynax S50 is the normal waxy type stuff.

I will be doing the underside of the car with UB and things like arches, boot lid etc with S50.

What is the best thing to spray both with, I hear that UB is thicker and harder to spray?
