Thanks for the tip, eBay queen, I just ordered a kit too. My headlights are still perfectly clear in the front where it matters for safety reasons but they're starting to show some hazing and crazing on top and it just doesn't look good - so I guess I should polish them in the next year or so.
One thing that bothers me about doing that though is that this polishing business will remove the hardcoat on the acrylic, making it easier to scratch the headlights from now on. Anybody have a fix for that or do you just commit to regular polishing from here on out? I remember a thread where a guy said he was going to follow up the polishing with some clearcoat but I don't think he specified what clearcoat he would use. I've got some left over from a CB350F restoration that would provide good UV and scratch protection but not too sure about spraying lenses with a solvent-based coating. Anybody tried it?
