How to restore your light bar domes! Federal Signal Aerodynic

This is a question I see asked all the time. How can I clean/restore my lenses. There are plenty of different ways to do it but here is a pretty user friendly option.

Thanks for documenting this process. I cleaned and polished my domes using this process and it works as good as advertised. The results are impressive. Thanks again for sharing. Now if someone could detail the reassembly process.

thanks brother i was worried that you could only do this with clear lenses

I was wondering how to do this on a dome, thanks!

I use 3M Finesse cutting compound then Flitz metal polish and finish with carnuba wax to seal them. I only sand if there's deep scratches, nice finish you got though.

Hey, how did you take apart the individual panels? I'm gonna start working on a project aerodynic of my own and I wanted to make custom lenses for it.

Interesting, I’ve never tried the finishing spray before. I always buff with plastx after the final sand. I wonder how it holds up.

[@emergencylightingbydeg]

In my experience it holds up well. I did the lenses on the Liberty that’s mounted on my POV just under a year ago and it still looks good.

Did you use the liquid on the headlight kit? Or just wet sand with the little soap and different grades of sandpaper with the spray sealant at the end?

[@emergencylightingbydeg]

In this case I did not use the liquid. I just wet sanded then sealed. If you have domes that are not overly damaged you can even try to simply buff and polish with no sanding at all.

Interesting how you jumped from 600 grit to 2000 grit. YMMV but typically I tend to not make such a big jump between wet sandings.. 600 or 800 to 1000/1200/1500 to 2000 etc..
PlastX works well as does Novus.. it's all a matter of personal preference.

[@emergencylightingbydeg]

If this were paint or if I planned to buff and polish these I would have done more steps in between. Using the spray on sealant though I have found that working it down to be perfectly smooth is not necessary and I still want some roughness so it can adhere.

Good job, but a suggestion believe it or not....to seal it after you Polish it and protect itfrom the elements. I use a thin coat of anal lube.. I usually get at the pharmacy and it seals and protects everything for years.. Since it has a petroleum base.
