At work (my real job), we have a Kawasaki Mule, which has a fibergalss windshield, which has been badly scratched up. I am going to try AIO on it, to see if I can clear it up. But should I use my RO, or go with hand application?
I would think your Kawasaki dealership has some stuff for those scratches. Other than that, what I've had the most experience/success with is Meguiar's Plastic Polish and Cleaner.
It's really made for plastic convertible windows, but I'v used it on all sorts of plastic surfaces, works great on CD's, with good success. It's not very agressive, so it may take some patience to bring them out.
...painted fiberglass, right? Not clear plastic? Just making sure.
If you are trying to cut it down and remove scratches, I'd say just go with the RO. I'm not sure if AIO [chemical cleaner] is exactly what you want as it might remove some of the paint in the scratches too, so you'll have to work longer...ok, that doesn't make a lot of sense.
No harm in trying AIO...I'm sure you'd see improvements from it by just using it by hand. RO would be even better [just a fast hand ]
You might want to try something abrasive if AIO doesn't do everything you wanted.
but you know how to treat paint...that is if this is painted fiberglass.
If it is clear plastic, AIO or the light abrasive might also work. I've never tried anything specifically for plastic besides Plexus, which is a great product, but it seems to be just a "glaze" for plastic in a sense.
My apologies for the brainfart. I was thinking _plexiglass_, but I typed "fiberglass" both times. And I was wondering why so many days had passed with no responses...
I took a pad and the AIO to work today, and did a 5 minute wipe down by hand. This really got a lot (maybe most) of the scratches out. Time didn't permit me to do this more than once, however. At this point I'm guessing that I could do this several more times, or just jump to the RO, and get it with once more.
