Thread: How to Restore Plastic Scales

I'm in the process of restoring a HESS 44. I've got the scales off, cleaned them, and gave them a good polishing with Flitz. This did wonders, but there are some very shallow surface scratches I'd like to sand and buff out. How high do you need to go with grit size before polishing? I've used 1500, then 2000 grit so far wet-sanding, followed by Flitz. It's better, but still not "wet-glossy" like the original! I know finer sandpaper is available----am I correct that I need to go much higher probably? My local NAPA Auto Parts store only had 1500 and 2000 grit, nothing higher, and that's all I've used so far. (followed by Flitz) This just doesn't get it "wet-shiny" like I'm aiming for. Thanks for any help!
