Step by Step Guide to Clear Plastic Headlight Restoration

headlight restoration before and after

In this article we take a look at Plastic Headlight Restoration. One of our regular customers recently pulled up outside our premises and asked me to take a look at his headlights which had become extremely clouded and dull over time from a combination of fine scratches and the effects of UV on the clear plastic.

Afraid that they were going to fail his upcoming MOT and not being able to afford a new set of headlights he wanted to know how he could restore the clarity back to his headlights.

I advised there are a number of different products available on the market which enable you to polish away light scratches, scuffs, haziness and surface marks from your headlights to leave them looking like new.

These range from single stage polishes, two step cleaning and polishing compounds to multi-step headlight restoration and protection kits.

Single Step Clear Plastic Headlight Restoration

Meguiars Plastic PolishProducts such as Meguiars PlastRx are single step products that are best used on fine scratches and haziness. The tend to contain a blend of micro-abrasives and oils to restore the clarity together with water-resistant polymers for added protection.

Whilst simple to apply, needing only a foam or microfibre applicator, they can however require a fair amount of “elbow grease” to get that like new finish. As some of our own customers reviews testify:

However being around the £10 and under mark they are very good value for money.

Two Step Clear Plastic Headlight Restoration

Meguiars 2 Step Plastic Polish & CleanerIf you are looking at potentially the next level in your clear plastic headlight restoration a two step method may be the system to look at. This generally involves a separate clear plastic cleaner and clear plastic polish – another popular system, again from Meguiars, is the Mirror Glaze M10 (M-1008) andM17 (M-1017).

Meguiar’s Mirror Glaze Clear Plastic Cleaner is a non-abrasive, alcohol-free Plastic Cleaner which aggressively cleans and removes hairline scratches without harming the surface.  Whilst the Clear Plastic Polish provides the second step to protect the previously cleaned headlight and leaving behind an anti-static coating that helps repel damaging dust and dirt.

Headlight Restoration Kits

Your final choice in DIY headlight restoration is a multi step kit. These are very effective systems combining extremely fine abrasives and polishes to remove the scratches and dullness from your headlights and followed up a separate sealant and protectant.

Whether using a kit or supplies from your local auto store the following steps will help to restore that like new clarity to your plastic headlights:

  1. First clean the headlights using your usual car wash shampoo to ensure all the dirt and bug splatter etc is removed
  2. Using a very fine 2000 grit wet and dry paper, work is over the surface of the headlight, keeping it moving so as not to concentrate in one area for any length of time
  3. Fill a spray bottle with clean water
  4. Fix a 2″ approx 5cm backing plate to your electric drill (ensuring it is one that does not operate above 2000-2500 rpm)
  5. To the backing plate fit a felt polishing pad
  6. Apply a suitable clear plastic polishing compundto the centre of the pad, place the face of the pad to the headlight and start the drill. Again ensure to keep the pad moving across the surface of the headlight. Do not keep the pad in contact with any one area of the headlight for more than 15-20 seconds
  7. As the polish drys out, stop the drill and using the clean water in your spray bottle, wet the pad and continue polishing until the haziness disappears
  8. Buff off any remaining polish with a clean microfibre cloth
  9. Next using a clean section or another clean microfibre apply one or more coats of a plastic protectant allowing it to dry in between coats.

Meguiars Headlight Restoration Kit

Meguiars Headlight Restoring KitOn the back of their already successful plastic polish and cleaner products a couple of years ago Meguiar’s introduced a complete headlight restoration kit.

  • – Woolen drill bit attachment buffing pad

  • – Finishing pad

It retails in the region of £17-£25 depending on where you purchase from, with some of the better deals being found online.

3M Headlight Restoration Kit

3M Car Headlight Restoration SystemFor many years a number of specialist suppliers would combine a number of 3M plastic restoration products and compounds to create their own individual kits.

Seeing the success of these products 3M then launched their own headlight restoration system.

This kit has gone on to become one of the best selling headlight restoration kits available.

It’s sucess is not only down to the quality of the products but also their attention to detail, even including the required masking tape within the kit.

Many other kit manufacturers leave this to the user to supply.

The 3M plastic headlight restoration kit also comes with a drill bit attachment as well as the abrasives pads and polish.

This kit retails around the £15-£20 mark.

Below is a short video of the 3M kit in action – just see the difference it can make to your headlights.

Quixx Headlight Restoration Kit

Quixx Headlight Polishing & Restoration KitUnlike the Meguiars and 3M kits the Quixx kit is not based on using a household drill. Instead in comes with a supply of sanding blocks and differing grades of fine sanding papers to use by hand.

In all the kit contains:

– 50g of Plastic Polish,
– a sanding and polishing block
– 12 sanding papers in a range of three different grades
– 2 polishing cloths
– a headlight lens sealer 30ml and

The headlight lens sealer included within the kit provides a hard and long lasting weather-proof gloss protection and a smooth dirt repelling surface keeps to keep your lenses cleaner for longer.

Not having to include a separate drill bit attachment this kit retails at a lower price point than the previous two at around £11-£14

Specialist Headlight Kits

Specialist Headlight Restoration KitOne particular manufacturer produces specialist kits based on the level of restoration required, not only for clear plastic, but also for glass. They have two headlight restoration products in kit form; one for deep scratches and also one for haziness, dull, faded or discoloured headlights.
