So not a bad video, but some recommendations or observations. Your process in general does work, the only part that I would omit would be the magic eraser. Also a more aggressive grit on sandpaper will be needed to go after domes in lesser condition. all in all though helpful for first timers.
Thanks for your comment! I am a big fan of these magic erasers, i also use it on the aluminium (lightbar) frames, its cleans really deep without scratching. (microfiber cloth will also do the job, but not using it...) As you say, domes with deep scratches will need lower grit sandpaper, but my experience is that it will take a long time to sand these out, and you get more scratches to begin with, that's why i don't go lower then 2500. Using this method is great for dull or faded domes, and will turn out really nice, but really deep scratches will remain.
How come you’re not supposed to wet sand the inside of the domes? The only thing I can assume is it would get rid of the color on colored domes, but that wouldn’t make any sense because the whole dome is dyed.
I’m going to try this method on a federal signal aerodynic lightbar. I want to try 2000 grit though cause of some scratches. You mentioned in the video do not wet sand inside the domes. Why? Thanks again for posting this video you did a nice job. I look forward to trying it. I won’t wet sand the inside until I hear back. Matt
in my experience 99% of the inside of domes are in good condition (because it's simply the inside, so protected against nature) basically if wetsandig is not needed, don't do it, just a good cleanup
Getting inside an aero dome isn't as easy with a polishing wheel. If you sand it and can't get in there to polish then you are in worse shape than you started.
Well these were intended to be replaced. For us in the vintage market, yes they are expensive but to a CHP fleet garage they were dirt cheap and probably had hundreds of them in stock.

Wonderful video, thanks for sharing.
Thank you!

A lot of work. Yet, well done sir. Too bad these light bars weren't manufactured with regular safety glass (like windshield glass) instead.
my guess then even less would have survived ;-)
