Need to polish a clear window made of plastic. Imagine a Guage lens or speedometer window. Whats the best for this? Going to HF and buying a small low speed foam polish head for the drill. Tried to buff it with a wheel and white rouge but it didn't work real well. Think it was too aggressive as I put very fine waves in it and didn't make it any clearer. I went up to 1200 grit wet sanding, as far as I had paper for.
 
i've had good luck with fine compound for buffing clear coat. Heat is your enemy so keep your
pad damp
 
Have you tried some Mothers Mag and Aluminum Polish?
 
I use the Mothers on My Motor home headlight's with good results.
 
1200 is a little course to start buffing. Depending the severity of the scratches/oxidization, I start at 600 move to 800. 1000. 1500. 2000.
I used to go to 3000 but found 2000 works good. I like Maguire's heavy cut for the newer heavy solids paint then follow up with their swirl mark remover. Pads can be too aggressive too.
Finish off with this **** and a microfiber cloth. https://www.amazon.com/dp/B00SS1EDMO/?tag=fabo03-20
 
That's the baby. Works well. Used it on 69 taillight lenses. First pic is the scratches. Second pic I buffed them by hand with the final polish and supplied cloth. They look wet.

Will that Micro-Mesh stuff work on cloudy late model headlight lenses? If it does, I wonder if it would be best to clear coat them afterwards?
 
On headlights I have wet sanded my 94 silverado lights with 320 grit, taped em off and shot 3 coats of automotive enamel clear. It held up for 15 years before peeling.
 
Saw that at the hardware store. 12.99 and Flitz was 13.99. 1 sheet of 1500 was $2.50..walked out. Have not bought sandpaper in years. Thought I could find an assortment for like 5 but they only went as high as 1200 in the assortment packs. Will look harder in the stash for some 2000 I remember seeing somewhere.
 
Polycarbonate polish is way too aggressive for soft acrylic dash lenses. Brasso has ammonia in it and im afraid it will craze it. Will try the McGuire plastiX stuff. Seems well rated, reasonable and I have a few things to use it on.
 
Works Well

One bottle lasts for years and years. Rub in firmly with cotton cloth to work fine scratches and haze out.

Let film sit and dry for 15 minutes. Then polish up to a high luster with a clean cotton cloth. Old T-Shirts work well.

Novice #2 works fine all on it's own.
