I personally think this Novus #2 fine scratch remover is a great product. I've been using it rather indiscriminately on just about every type of plastic surface I can find and it really seems to do a decent job with the vast majority of things I've tried it on so far. I don't even bother using their #1 plastic cleaner product first.I've tried other plastic or acrylic polishing products over the years, but they all seem to just fill the scratches with wax or some type of oily film that evaporates after a couple of days, leaving the surface looking as crappy as ever. This polish actually buffs out most of the small scratches and leaves a shiny, polished surface that really lasts.I've used it to remove the small surface scratches on the displays of my expensive Fluke Scopemeter and favorite 87-IV DMM, as well as my old Fluke 36 and newer 337 clamp meters with surprisingly good results.It brought the eye shields on my bench grinder back to life after I accidentally dripped clear PVC primer on them while installing a new drain line overhead. I never thought that the etched opaque spots the primer left would ever come out, but this stuff has made them crystal clear again. With that in mind, I also tried it on several pairs of scratched up safety goggles and a face shield that I normally would have thrown away, but they are now all completely usable again.I had some old Craftsman screwdrivers with clear plastic handles that had some kind of scum adhered to them. I used this stuff with an old T-shirt to polish them up. They now look better than they have in years.  I also used this on my older Klein cushion grip screwdrivers. It did a good job cleaning the crud off the black rubber grips as well as the yellow plastic parts of the handles and it even shined up the chrome on the shanks.I started looking around for other things to use it on and so, I polished up the clear plastic gauge faces on my Oxy/Ace tote-a-torch regulators, refrigeration manifold gauges, well pump pressure gauge face, boiler pressure/temp gauge, dashboard gauge cluster in my truck, vinyl grips on several pair of pliers handles, the cushion grip handles on my lineman's pliers and wire strippers, the clear chip shield on my plunge router and jig saw, all of my other meters and test equipment displays, the digital display on my Dewalt work radio, three cordless flashlight lenses, two cordless fluorescent work light lenses, my Mini-Mag LED flashlight lens, my LED headlamp lens, two thermal label maker displays, two clear plastic clock bezels, my cell phone's display, a fiberglass step ladder, our fiberglass shower stall, the headlamp lenses on my wife's car, and on and on. I even tried it on an old Klein polyethylene plastic hard hat I had laying around. Of course, it wouldn't take out any of the scratches on it, but it did make it shine like it hadn't in quite some time.Based on the results I've had, I would have no problem recommending this Novus plastic fine scratch remover.
