I was putting the finishing touches, a light polishing on the bike before covering her for storage and with the first pass I ruined my Klock windshield. I am so glad it was the windshield and not paint or chrome. I laid the micro fiber towel on a roll away stand I have in the garage with my supplies on it as I clean or work on the bike. When I went outside, I guess my wife swept the stairs leading down to the garage and some small gritty pebbles landed in my polishing cloth. She didn't think when sweeping and I didn't know she had done it till it was too late. Bad enough that no polish will take them out. A new windshield has just been added to my Christmas list from Wifey! It could have been much worse if I had started on the fairing or tank. Thankfully I started on the windshield.
I'll certainly take your word for it that no regular polish will remove/fill the scratches, but wouldn't a scratch remover compound be worth a try (given that its a ruined windshield anyway?)
I would get novius (spelling) #1. #2, #3
Start with #3 and work your way down..
If you have buffer, vibrator type, it will make it a lot easier. If you can feel the scratches you will have to sand them out first.
Maybe more suggestion will be posted.
A new shield may be in order any way.
Yeah guys, I tried Novus as well as Safe Cut. The shield is the dark smoke so I'm limited on how much I can buff it. I tried but results indicate its new windshield time. As I said though it could have been paint or chrome. Glad it was just the shield. Wife felt terrible
Long Ride medium smoke tinted shield with a 2 inch scratch caused by a loose pin in the cardboard box I had it in.Deep enough to feel with a fingernail,came out good as new hand buffing with Meguiar's Scratch X and a micro fiber cloth.
They make all sorts of kits for getting scratches out of plastic headlight covers. I would use one of those on my shield before I gave up and went for a new one.
Back in the day I would use a product called Micro-Mesh to polish out canopies on tactical jet aircraft. I remember working (starting ) out with 800 grit wet paper to 12,000 grit polishing paper and then cleaned it all up with plastic polish. Saved big bucks using those kits.
