Some excellent info D. I used to spend a lot of time buffing plastics and metals so a lot of this is familiar, but that was long ago and all I have left is some assortment of rouges and a few buffing pads.

The video is excellent BTW. Good to see things get chucked as I'm very familiar with the effect, except you can snatch it up again like a Duck on a June Bug, for me it's usually gone for good.

I personally like using McGuires compounds (for automotive lacquers and  glass) since I'm familiar with them and have stash from my car painting days. Same general thing, finer and finer grits until you are using bunny butts.

The slow speed grinders are probably the best tool to have, but over two minutes? Geeze! With a high speed unit that time could be halved 🤠
