I have about 20 4x8s hand painted aluminum signs. Used 1 shot without hardener. They are getting a bit chalky after 2-3 years. Could some of you fine Letterheads suggest a technique or a product to bring back the color and gloss. Thank you all all in advance.

Hi Bob, sign refinishing clear will work. clean them off and give them a good fine spray, they will look great!

Since they're seasoned, I'd use a catalized top coat like Matthews. It's best to spray a light coat followed up with a flood coat after a thirty minute break.
This isn't possible with freshly painted One Shot.

soap....water....sponge I's just like a brand new car. If you just parked it outside for 2 or 3 years, this is what happens, After you clean the panels, just put a coat of automotive wax on. This works great!

I agree you can wash and wax but that won't reduce the UV penetration.
I've been re-lettering signs for the Univ. of Oklahoma for years which have a big fat coat of Matthews clear. For updates I wet sand the portions that need changing and start all over. The university requires all signs to be topcoated this way. They sure look clean and stay glossy for year. But, it is more expensive and takes some spraying skills.
