Hi guys...............Look, I'm just an old, experienced motorcycle rider. The latest and greatest techy stuff and I just don't click.
Having said that, the ferret and I wholeheartedly agree on this topic (sorry, Mickey

) PLEXUS RULES! I have used it for several years now, and I have to admit that my face shields actually last longer than my helmets! Just kidding, sort of.
Since I discovered Plexus several years ago, I have yet to replace a face shield due to scratching issues. I ride in the mid-south, where bugs, bees, locusts, etc are the norm even in the daytime. I have had the same face shield for 4 years now, and after a good cleaning with Plexus the shield always turns out to be scratch-free. The product is simply amazing.
Also, with today's paints and their polymers, Plexus also works extremely well on fuel tanks, side covers, gauge faces, mirrors........
pretty much anything.
Spray on, wipe with a terrycloth towel, and you're done.
IIRC, Plexus was originally developed for fighter pilots to keep their windows/shields clean. One helluva product.b

Even though the price has risen considerably the last few years, I still consider it a bargain, and I just can't imagine owning a motorcycle without this stuff.
I also use on on my Camry's headlights..................95K miles and ZERO fading or clouding.
