Removing scratches from Ninja 250 Windscreen

I decided to spraypaint the inside of my stock Ninja 250 windscreen. It came out great, but the problem is the front has a lot of swirl marks, road debris scuffs, etc. They aren't deep, but it needs a proper clean and polish. Washing it doesn't do anything, so I need some sort of chemical/product.

I'm worried about just heading to Canadian Tire and buying something like Meguiars PlastX, because I don't know what material the windscreen is actually made of. I know some compounds are meant for certain types of plastics, and I don't want to ruin it by creating more scratches.

Can someone recommend a product? And should I apply it by hand, or attach something to my drill?

Thanks kindly :)
 
No, I've been down this road already. The aftermarket ones vibrate like crazy on my bike so I need to stick with stock. And a stock windscreen does not cost $20. The eBay knockoffs cost $20 which vibrate when my engine hits certain rpms
 
I put a zero gravity on a girlfriends 250, no vibration.

What kind did you try?

I had an older 600 that used to vibrate, little foam pieces where the bolts went thru (underside so wasn't visable) did the trick.

Google polishing a motorcycle screen. Seems to be two real options short of replacement - try a plastic polish or progressively finer sandpaper.
 
I'm happy it worked for you. I bought a $20 eBay windscreen. I'm not gonna buy a $100 replacement.

i just need a product that works. I can't believe it's this difficult to get a straight answer on a specific product that's available from big box stores like Walmart/Canadian tire etc
 
Do you know what type of plastic it is? Polycarbonate vs acrylic?

You will need to know that first before you try any chemical products.

No I don't, i expressed this same concern in my original post.
I decided I buy Novus
 
If the plastic headlights on my former 2001 civic are anywhere similiar, you really don't have a GREAT option.
Sanding will get rid of any UV coating that will net you yellowing plastic in a few months
Plastic polish works so-so if you have a professional machine (orbital or rotary)

The only long term solution I had was to plastic polish first to get rid of most of the swirls/minimize deep scratches, and then apply a clear plastic film (similar to lamin-x/ventureashield). Between the film and the bit of water you use to position it, it becomes a 95% flawless finish in terms of optical-clarity. The film gives the UV protection, ongoing protection, and hides the remaining swirls that is hard to remove from plastic.
