I had great results using the HD on a red TSX. The wax has been on there for about 3 months and is still beading/sheeting water great! The slickness is not amazing but it does look deep/shiney on a light color like red. For $35 its worth having, give it a try and see how you like it.
I would love to try them i just cant bring myself to spend that much on one spray bottle. Im sure they are worth it i just need to break down and spend the money haha
