Now how does this stack up to the leading meguiars headlight leans protector I would asume it last's longer do to the fact that its a coating or no? If anyone here has ever tried the meguiars one please post your overall thought on it. from my experience with it, it works quite well and last a good long wile.
"The leading Meguiar's headlight leans protector" doesn't exist.
Meguiar's has a headlight restoration kit with a hand buffer, 2 sanding discs, some plastic polish, plastic sealer (which really isn't a sealer at all) and a drill attachment for buffing, are you talking about that one?
Meguiar's also has a professional kit that also includes 4" pads for doing spot repair, plus a LOT of sanding discs, everything from 500 grit to 3000 grit and it also includes a small bottle of M105 and M205. Is this the one you are talking about?
I only ask because the first one you can buy at your local parts store for $30, and if you put enough time in it you can get decent results. But unless you break out a DA buffer you're really fighting with yourself when using it because it's just a hand sanding pad and a synthetic wool drill buffer. This one I bought years ago and used it on a set of headlights that were in decent shape to bring them back to life, but if they have failed (in that the UV coating has become hazed and foggy) you'll need more.
The second kit I also have, (normal retail $299 but AG has it on sale now for $125 and it's a KILLER DEAL!) You can do any lights you might run across with this one and it'll finish them out to a fantastic level.
However... once they are finished you MUST put some sort of coating on the lens. The stuff that Meguiar's offers isn't a coating, and it really isn't a permanent sealant either. It's more of a lotion than anything. Think of it as suntan lotion for your headlights. Unless you reapply it with every washing the lights will fade again fairly quickly.
Remember, when you do a (major) headlight restoration it's usually because the OEM coating has failed. Once it's in that condition the only thing that will help is to totally sand and remove that coating, getting back to the polycarbonate headlight itself. Thing is, now, although it's nice and clean, clear, and shiny, it has NO protection from UV damage.
This is where Opti-Lens is different than the "lotion". It provides a permanent coating and will protect your newly restored headlights from fading and further UV damage. Plus for even greater protection it can be "layered". It will not wash off or will not wipe off. Oh, and fwiw, the 10cc applicator should be enough for 5 to 10 pairs of headlights.
