Optimum Optiseal minimal UV protection

So the blurb for Optiseal says it "blocks out dirt and UV radiation"
Not sure how much it blocks but it's not enough to stop headlights from yellowing.

Usually after polishing my headlights I apply a coat of Gtechniq C4.
Keeps the clarity for a year or so.
3 months ago I corrected the headlights again but thought I'd give Optiseal a try seeing as I had it in my arsenal anyway.
I applied it EVERY week after a wash.
No way near the protection from C4.
Yellow back again.
So if you're thinking of "blocking out UV" after headlight correction, don't bother with Optiseal.
My car is tucked away in the garage while the fresh coat of C4 cures on my lights.
I'll try a second coat of C4 tomorrow and see if prolongs durability.
I'll continue to use Optiseal for a quick wipe over on my wheel faces after a wash and dry as it's so easy to apply with no buffing.

I worry about this too, with all the sealants that can only be a few molecules thick on your paintwork. Looking at you Gtechniq C2v3 and Gyeon Cure! Especially when theyre sold as being usable as standalone LSP products!

Optiseal is no way meant for this purpose, they do however have a dedicated headlight coating to be used post correction

Optiseal is an amazing drying aid but I never got on with it as a stand alone sealant

During a DW trip to Autoglym, we tested their headlight restoration kit (very good it was too). We asked their head chemist about protection once the headlight was restored and he said that there was not much that would prevent the headlight from going cloudy again after time. They had tested a number of coatings and none had an appreciable effect.

What could you do to protect headlights now,
So they don’t yellow down the line?

£59 for preventative maintenance. Seems like an expensive solution. I got a pair of replacement headlights for my Colt for £55.
