Interesting, do you have any pictures before and after? kinda curious.
You can PM link to save the hassle.

 

use rubbing compound to bring out the clarity.
the 3m kit is good

 

I just use the 3M kit. Takes less than 15 minutes per side and they come out looking like brand new.

Far easier and quicker than hand sanding/polishing.

 

I've been doing headlight restoration for years and I actually get a lot of customers that are evo owners.

To answer the question of this thread, you need to polish the headlights after sanding as well as protecting them. UV Sealant will work, but make sure you use it from time to time to prevent them from oxidizing again.

Clearcoating them is NOT the way to go. Clearcoat's meant for paint, not seethrough plastic lenses.


Here are some samples that I've done:

 

Thanks for contributing. I went through wet sanding in this order. 100g-220g-400g-600g-800g-1000g-1500g-2000g-2500g. Got all the nasty oxidation out and was ready to throw compound, polish, wax, uv protection but noticed I have a good amount of scratches. Not a lot but enough to bug me, any ideas?

 

I need to get mine redone. But mine look weird from the inside of the lense hopefully I can pop them open and make them nice again

 

In most cases it's the outside, unless you've previously opened them up before.

 

Can anyone show or at least do a diy for this with pics step by step? my left headlight looks a Lil hazy just a little this would be a good project for me and others to view.

 

I used this kit the other day and my head lights look amazing. It was simple and had step by step instructions.

Well here's the day and bid of the lense in progress and what it looks like when finished.

 

is there anything that can be done in order to prevent this from happening? Any type of tint that can be applied in order to prevent the haze?

 

You can only slow it down from happening but its inevitable over the months or years. That's nature for you.

 

You can get the headlight Wrapped with the clear bra

 

a clear bra can prevent the headlights from getting hazy?

 

I have been through a few headlight restoration kits and have never been happy with the results as they would still come up a bit cloudy I did the following and they come up like new.

items needed
1000 grit, 1500 grit, 2000 grit wet and dry
Plastic polish like Plast X
methylated spirits
Urethane (for wood)
Mineral Turpentine

Sand as you normally would alternating directions as you change grit.
Polish with the Plast X in circular motions.
Clean with metho.
tip wear disposable gloves for this next stage
Mix a small amount of uethane and turps 1:1 and get a rag to wipe it onto the headlight. This will be the sealant. Cure for 6 hours at least.
