Finally got around to getting some this weekend, intending to use it on the visor. Says not to use on plastics, and that confused me as I'm sure I've been advised it's a good thing for that? Will it be ok on my Sparco???
I supose I could use it on the cars too come to that!
I have used on visors without problems. However I have only used it when Im sure its going to rain. Bearing in mind that I clean the visor every couple of hours anyway, so the Rain X is not left on for long periods.
