Polishing your helmet

[clayt74]

I've had 2 visors ruined by using normal Rain-X before, they ended up looking like they were covered in diesel.
I know some people use it with no ill effects but it's definitely not suitable for all visor makes.
Plus it's designed for glass anyway!
There are other similar brands designed for plastic, but i've yet to find one that works at all on my Arai visor, rain sticks to it like oil droplets, which is why the Vee Wipe is so important for me when it's raining.

+1 for the Vee wipe best £6 i ever spent
