800 grit is the best finish You have to give the clear coat something to grab on to 2000 grit only gives you a small area for the clear coat to grab on to
One thing I would add would be after the clear cures properly wax and keep them waxed. I have done this with my Ford Focus since 2007 and never looked back, they always look new.
That's a ton of different steps. I would try just using your DA with compound as step 1. You might get most of it out without the 7 different sanding steps (I did).
A lot of folks weighing in here - Show the result of your method at 1, 2, and 3 years and that will determine which is best. Also, bear in mind environmental factors, amount of daily sun exposure, climate, and owner care in maintaining the vehicle are huge factors.
If there is literal moisture droplets, then it is on the inside due to a failed/faulty seal on the housing. That requires different methods of repair. But outside yellowing is oxidation build up on the polycarbonate lens 👍🏼
Actually, I have achieved clear headlights plastic enclosures without the use of the electric buffer. You just have to buff more vigorously with your hands. If, you park your car in the summer sunlight. In due time, the yellowing will return. Depending how well a job you did. First-time.
Not using a buffer gives you worse results. A DA polishers imitates what your hand should be doing, flawlessly, every rotation, with even better pressure & results with less effort. By hand is just a waste of time. It’s like saying why use an impact wrench if you got a pair of channel lock pliers…
Tape will need to be replaced because Polish dust and spraying soapy water will ruin it anyways. You will need a fresh and clean one before spraying clear coat.
@@VardhanShrivastava im saying i think your response is dumb. Its not that much more expensive. My jeep has glass headlights and they were like 100 bucks for both at autozone.
@@jeepowner2675 'it's not much more expensive'?do you have any data back your claims up? Do you work at an Automobile Manufacturer? Just bcs you think something works certain way doesn't mean it does.
This is the exact way a Bodyshop would do them. Some errors You may need to go to 600 grit wet which is really the lowest you should go You need to do a cross pattern 600 vertical 800 horizontal, your sanding off All the old existing clear coat. You need to use a sanding block to distribute the pressure evenly You may not need a wool pad you may use an orange pad You want it uniformly dull as in sanding off a clear coat that has failed Everything else is 100% correct You must use 2k clear that’s what’s on it originally because it’s solivent proof pretty much, 1k is not go through a car wash bug spray gas ect. You also better mask up the whole front of the car. 2k clear overspray is near impossible to get off Also use the Can within 24 hours This is the only correct method for Permanent Also if you don’t wanna use clear seal it with like a legit synthetic sealer- jescar power lock or like any coating system - this Will make it semi permanent Also if you have little small cracks doing this will make them 10x more noticeable Aftermarket headlights are not as good- they leak and are not sealed a quality aftermarket or oem is fine This Can be avoided by garaging your car or truck and treating the headlights like paint wax or synthetic sealer to protect the clear coat It’s failing clear coat on plastic due to Uv light Also I have a mid 90s mercedes with glass headlights. In usa mid to later 90s dot outlawed glass headlights - during accidents they caused more damage then the accident and it resulted in increased injuries. I personally love glass headlights. Hope this helps someone If you don’t have a sanding block use a sponge.
Completely unnecessary going through all those grits, if you are going to clear coat it in the end. You only need to go something like 400, 800, clear. Done. That's what auto painters do...
Should have used a foam pad with your sandpaper for uniform application. We start 600-1000-3000 with drill attachment and blow this out quick. We sand cut and polish aluminum/stainless to perfect mirrors using airway pads. I’ve also used white diamond metal polish on a flannel buff with rotary. No sanding needed, removes oxidation and comes out perfectly clear. But that’s my little secret go easy 700 rpm on a 3500 rpm makita with flannel airway
@@Askyourmother424Oh damn I have sandpaper scratches and lowest I go is 1000 grit and i use meguiars 105 cutting compound and meguiars 205 any recommendations to get rid of those marks ima get a cutting pad soon you think it would do the trick?
@@dinozr2784 Also ease on the pressure when sanding and let the sandpaper do most of the work. After every step make sure to check for any remaining scratches from the lower grit. If you do every sanding step like this there should be no need for a heavy cutting pad.
Why would you clear coat with 2K clear coat? It’s not made for headlights. Wait until it goes bad in about 2 years. Was a good process until you put 2K clear on it.
Лак сняли полирнули и толку ?Через время она станет мутной если не нагести спец лак для фар .Нанесите лак и прозоачной плёнкой обтянуть вот тогда будет толк на длительное время .Или вариант купить новые фары и обтянуть их бронепленкой .
You're not going to believe this and i don't necessarily recommend it. But i use brake fluid and scrub it in with 0000 steel wool until all the yellow crap comes off. Then finish with a light layer of linseed oil
400-800-1200, machine polisher and a heavy cut compound from literally anywhere. Then a cheap can of clear coat. This is way over the top on the sanding
If you are going to clear coat the lights there is no need to polish them. In fact, if you don't get all the polish off the clear will not adhere properly. You are far better to sand it down to 1500-2000 clean the lights off and clear them.
I believe it's almost always worth it to restore headlights rather than replace them. Even if the headlights don't cost a lot for a vehicle, the cost and/or, time and work to replace headlights can be A LOT ! Not to mention the chance of chipping/damaging paint removing + reinstalling panels + parts. Some cars require bumper, grill, body panels, ect... to be removed..... It doesn't take much time, effort, money, or supplies to restore headlights. ANYONE can do it. And, why replace something that Doesn't Really Need to be replaced. Just my opinion though....
Do you have any idea how much work it is to remove headlights, install (probably extremely expensive) new ones, AND make sure they're aligned properly so you aren't blinding people when you turn them on???
Depends on the car. On a crown Vic you sometimes see headlights sell for $40 A PAIR.. not worth the elbow grease. However a Mercedes, BMW or even a Volkswagen it may be cheaper
Wow, a lot of unnecessary sanding, one good sanding with 1200 and then a cut polish like glasurit fine white polish and a wool buff and whala a new headlamp emerges.
Wow.. why not just use a da sander with 3m paper n go up to 3000 trizac. Then buff.. better yet use the 3 m kit. Hand sanding without some type of pad is useless. There is no way to get even pressure. And for the love of God, stop using that dime store painters tape. If you used a quality auto body tape.. like 3m, you could stretch it around the curves. Eliminating the need for a hundred ripped off pieces.
This is your business.... don't show your business secret.... then no point in doing business..... Bcoz after seeing this video....if a car owner ask you to change the new headlight set.... Even though you change with the new headlight set...he thinks that you just rubbed and polished with the old one...he won't believe.... never ever show your business secret in video to the public.....
@@TheFatSandwhich this is the thought process of many fools. That's why $1500 video editing course now available for just $10 in the form of video editing app...EOD end users enjoy but the business and business people are in trouble...
@@moneygold273 Right, but if a business did claim to replace headlights but actually just restored the old one that that'd be scamming wouldn't it? What sort of reputable business would take that kind of risk? None
