i don't see any cracks or crazing. it's just uniformly milky. i polished a long time with the DA polisher. the plastic looks smooth and shiny. but milky especially from a side angle or an off angle from the driver door. If you look straight at the headlight, you can see the inside 75%. 25%...

I test sanded part of my headlight (circled in red in photos) for a long time to see if I could restore transparency to the polycarbonate. Used 600, 1000, 1500, 2000 grits, then polished with rubbing compound. No matter how long I sand, I just can't get rid of the milky appearance. especially...

you suggesting both will fail at about the same time?

my car is almost 14 years old. The clear on the roof has failed and is peeling. The flakes coming off are less than a fraction of paper thickness. Is new clear coat as thick as several sheets of paper?

do you have pictures? close ups? orange peel on a headlight will cut down on light output. When I tried clear coating headlights on my other car years ago, I could see the fine scratches at night when the light was on. My GS lexus headlights are all yellow too, but a light buffing every...

sounds about right. My other car is 13 years old, and I think it started failing at the 12 year mark. Trunk and roof are bubbling. It's also a light silver color, so I imagine darker colors would be even sooner. I know I can get it a lot better with compounding. I just don't know how thin...

My car looked great at 5 years old too. if only you could see what your car would be like in 15 years.... that would be a great longterm test.

The stupid thing is that I use my garage for storage. I would use a car cover, but it's such a pain to remove and cover again, and the dust that accumulates on it gets on my clothes when I remove the cover. I did buy a bottle of Nu Finish liquid sealant recently, and they claim they tested...

Yeah the paint is clearly dull. no doubt about it. A marked difference vs the vertical surfaces like the doors. I've never polished or waxed the doors since 2007, and they look new. Since 2007, I've only waxed the horizontal surfaces regularly, cuz I know what the california sun can do, and I...

Oh, I don't wax my car every week. I do it every month. I'm just wondering whether weekly waxing would even offer any long term protection. I know for sure any wax does not last more than a month in the LA sun on my smoky granite car. It's a 2007 lexus smoky granite. The paint is nothing...

if a car sitting outside and waxed every week still gets clear coat failure, why even bother waxing at all? If clear coat gets hazy, but can be buffed back to a shine, is it pretty much too late to save it? point of no return? I have a 2007 dark gray car, and the roof paint has gotten hazy or...

you do several more steps than me. I'm lazy. I just claybar, then 845. done. I really don't want to spend that much time on my car. I'm only doing it for paint protection, because all my older cars had failing clear coat, and I want to try my best to prevent failing clear coat on this car...

Sounds like I'm seeing the exact same results as you. My paint color is smoky granite mica, which is pretty dark. Final rinse of the car, and the water is stuck to the paint when I try to blow it off with leaf blower. I definitely expect a white car to have longer lasting results. Those cars...

my car is near-black color. I honestly think the heat deteriorates the 845 wax. I can cook eggs on my car.

paint is still intact. I claybar, then wax. I'm looking at beading after washing. After final rinse

Just wondering if anyone has been able to get 845 to last more than a month on the hood, roof, and trunk panels...when parked outside in the sun all day. When I wash the car 30 days later with meguiars car wash, the horizontal surfaces don't bead water anymore. You guys who can make it last...

2007 lexus. paint is in good condition. No peeling or anything

ok today I clayed and used more 845 than I usually do. did 2 coats on the roof. 2 months ago, I 845'd around the gas tank cover, and it still beaded water today, whereas the roof and trunk were completely flat and a sheet of water just stuck to the paint. So that leads me to believe the sun...

meguiars says deep crystal doesn't strip wax. I've occasionally used Dawn before waxing, but mostly I just use a claybar. Tomorrow I'm going to clay and do 2 superthin layers of 845 on the roof. I really want to get the 4-6 months everyone else is getting. In the recent past, when I waxed 845...

meguiars deep crystal car wash. I only wax the top surfaces- hood, roof, and trunk. and it's always the trunk and roof that no longer bead the soonest. Next time I wash, I'm going to try 2 coats right after the wash to see if that makes any difference in longevity.
