Gtechniq C4 performance on headlights

[HEADPHONES]

Corrected my fading headlights last year.

Put a coat of C4 afterwards.

Alas the cloudiness started to return.

So unless I didn't apply correctly it's lasted only a year.

C4 has lasted well about 4 yrs on my Mini's abundant exterior trim but alas fairs less well on the lenses.

The new oxidation was minimal and was removed with Meg's metal polish by hand in a couple of minutes.

 

I'll reapply with C4 and maybe top up with C2v3 every few weeks or so when I use it on the paintwork.

Thought I'd just post up my experience in case others were expecting years of protection from C4 on lenses.

How did you correct the headlights?

Last year I used a cheap Silverline random orbital sander that was recommended years ago on DW, with a menzerna orange pad, some menzerna fine polish and then cleaned down with some apc.

Coated with C4 and garaged overnight to cure.

Yesterday just needed a hand polish.

The APC wouldn't have helped the C4 bond so there's a likelihood that, that would have reduced the durability somewhat. For best results, stick to an IPA wipe down prior to coatings.
