Fuyoh, nice work bro.
Not many willing to go thru headlamps restoration [myself included] cos phobia with wetsanding etc. Interesting though.
Kudos on the awesome end results! :thumbsup:
Thanks bro

Truth be told I also phobia wet sanding (even though 3M made it a lot easier with their disc + water application) and maybe that's also what caused most of the procrastination.
In hindsight, it really wasn't that bad
Applying the clear coat was actually more challenging and I fucked up the second headlamp. (Had to re correct and level the clear coat so the durability for that one headlamp is probably compromised)

Nice outcome! Do you have experience with the 3M coating? I wonder how long does it last under Msia weather. I bought Samurai 2k clear coat... but never dare to use it haha... this does look "safer".
Thanks bro

Nope first time.
And yes botched a headlamp.
My experiences and tips for anyone who's interested to avoid pitfalls I've encountered:
1)Having a A fine polishing compound, such as Meguiar ultimate polish or PlastX will yield a non hazed finishing.
However 3M didn't advise about it and supposedly, the hazed up (rough/uneven finished surface by the 3000 grit) may promote better clear coat adhesion? Something I'll find out from that one successful headlamp within 1 to 2 years time.
2) During application, having no rain and preferably no wind (especially if dusty environment) is preferable.
It's like car paint clear coat. And dust will ruin it. Hence good car painting does it in sealed environment and very pro ones will wear like hazmat suits lol
3) Some alcohol wipes (or IPA) could come in handy before the clear coat application so better adhesion and maybe better durability
4) drying is only 20-30 minutes and fully cure is within 2 to 3 hours. Advise to let it cure a day (my own paranoia and assumption lol) before driving out.
5) Here's the challenging part:
Do not spend more that 5 minutes to apply it
Only a single crossed linked/overlapping coat is enough
6) if it happens to start to dry
Your headlamp is fucked lol

Nothing to fear about wetsanding as long as u practice the least aggressive method first. Even on paint the likes of 3000 grit sandpaper is easily polished off without significantly removing clearcoat. Only through trial and error then will know which grit of sandpaper is safe on cars and which is not.

Yeah agreed especially consumer targeted products.
Somemore American 3M
Their consumer power/lawsuits scary

Now having a velcro/drill attachment would make this a ton easier.
I only did it purely by hand, and let's just say few hours (in total actual work) rubbing a small same spot, alternating between both hands, is pretty tiring

As 3M disclaimer and FAQ mentioned, 3000 grit is very safe on thick plastic headlamps much safer than car paint clear coats. Mistakes and errors are also more forgiving and easier/better chance for correction (in the event you screw up)
