Headlamp restoration - clear spray lacquer?

I'm soon going to use the 3M kit that attaches to my drill to restore my Lexus LS430 headlamps. I originally brought some sealant, however, I have now read that this won't last, and that I should use some clear lacquer spray which should permanently protect the headlamps. Sound okay?

Just wondering if anyone can recommend a decent lacquer spray that will do the job? Non yellowing and UV resistant?


Couple of possibilities

if I was you I would just use the sealant and top up every 6 months, your best bet would be some ceramic sealant.

Imagine if you polish your paint, you wouldn't re-lacquer that, you would keep the protection topped up, think of your headlights the same.

Applying lacquer outside to a clear surface wont be easy to get a good finish

When polishing paintwork you are not removing the lacquer or protective layer as you are with doing headlights. Because when I headlight goes this way the protective layer has already worn away and you are sanding not polishing.

So it's quite different

Re applying lacquer is the best method, but certainly not outside. Take the headlights off and do them. If not then prep and clean properly and apply a ceramic coating.

I've never had luck spraying clear coat on headlights after a polish. I want to try putting a sheet of paint protection film next

So polishing a car doesnt remove clear coat (lacquer) best tell the news papers as every one must be miss informed.

Polishing paint removes lacquer, Polishing your removes lacquer.

Re-lacquering headlights vs sealing them if a big difference and to get good results with Re-lacquering you would need to take them inside, properly prep and leave them to cure, most people don't have someway they can do that, or 24hours to leave headlights of their car, I have to take my bumper of to take mine out ffs and with the substratebeing clear plastic any imperfections would be more visible.

We ALL KNOW Re-lacquering is the most durable but not the most piratical

Maybe good to polish with but don't count on it for your protection, grab a polymer sealant im using Detailer's Pro Poli-Coat Paint Sealant and just keep it topped up when you do your paint

Even with polymer sealants, the headlights are going to yellow up again in a year. The Griots Garage system has a spray can clear coat to recoat the lights which will provide proper long term durability. Otherwise, you'll be re-polishing every year.
