I've always got the inkling that it's a carnauba wax with various synthetic sealants mixed in. It's certainly not just your run of the mill carnauba wax, and it's certainly not just a sealant due to the carnauba content.
I do wonder, could you just compound and polish the trim areas and then top off with a sealant? Seems like that would be a more permanent fix than rubbing product on them to darken them.
Looks like the subsequent steps weren't carried out for long enough, i.e. the 800 wasn't used for the length of time needed to sand the 500 marks, and so on. He also could've gotten a contaminated disc that put those in. I'd use what's left of the kit and start from scratch with the 500 grit and...
And just to add for the OP, Meguiar's Headlight Protectant, according to Mr. Stoops, has much more UV blocking capabilities than most regular waxes and sealants.
I think he's trying to prevent the factory coat so it won't fail eventually. They don't just fail willy-nilly; they fail because they've absorbed all the ultraviolet they can handle. So it quit absorbing and starts transmitting, and that's when the polycarbonate starts oxidizing.
And I'm not...
Hey there. Funny you should comment on this thread. I was just about the update it. I just replied in the thread you started, but basically just two choices:
1) Diligent monthly applications of a synthetic sealant or wax. I use Meguiar's Headlight Protectant. They (Meguiar's) say that while...
I slap a coat of Meguiar's Headlight Protectant on mine about once a month. If you really wanted to protect them you could Opt-Coat them and do monthly Meg's HP rub downs.
I like to do it by machine. By the time I'm done washing, claying, compounding, wiping, polishing, and wiping, my shoulder is screaming at me and threatening to go rogue and hoof it to Mexico. Machine waxing/removing is just easier for me.
Pretty darn good turnaround! Just curious, why not go over it again with a white pad and some Wolfgang Finishing Glaze or M205? It'd probably finish out nicer and look better with the sealant.
