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.
