After 4 months there is a definitive streak on the lens approximately between where I moved to the next section down to apply the clear coat?

This is the second time I have cleaned my headlights with the Sylvania Kit and the first time I messed up by ding something similar to what you are talking about. I found the best way the second time I did it was to start at the top of the headlight and work in a very broad sweep to the bottom corner. It seems the work fine and my headlights are still just as clear as they were the day I cleaned and sealed them. The first time I noticed that I tried to touch up a spot and it messed everything up. So, next time around, I used a large enough cloth and enough clear sealer to seal the headlight in one broad sweep from the top corner and worked down to the bottom corner in one large sweep. Worked just fine so far they are great.

No, it's not dust in lens. It is moisture condensation. Now, the camera is dry. Every picture it took is great without the ghostly translucent round spots. Guess the problem I have is different from yours.

I left a review. It looked like new for a few months. Then it developed a haze. The clear coat seems to become opaque. It does scratch easily also. After 1 year I re-did mine because I hated the hazy look again. It was much easier to de-do because most of the oxidation was already sanded off last year. I prefered the Wipe New due to easier to use sanding pad and pre-soaked clear coat micro fiber patch applied it evenly and easily without runs or dripping. I used the rag afterwords on the black plastic trim and tailight lenses to amazing effect. I expect it will also haze after a year and be hard to remove but it looks fantastic for now.

I've been using it for about month and I can see a little difderence. My lashes are a little bit longer.

I think a lot will depend on weather conditions and how often the lenses are cleaned and polished. Sand and hot sun take their toll. I'm sure at least a year, probably 2 or 3 if the lenses are cared for in the interim.

There were no markings on mine either plus it leaks. After a few days of rain it has gotten condensation inside the lens.

When mine did that, it was simply a dirty lens. I cleaned it with a microfiber cloth. As the lens is plastic, is it possible that some substance came in contact with it and turned it cloudy? Sorry, these are the only simple things I can think of

My lens is very smooth & quiet. We did have an issue with dirt inside the elements of the first lens and had to get a replacement. I suspect their manufacturing is not 100%

Not on either the surface of the lens (back or front), nor anyplace inside the lens. Check to see if there is anything on the surface, although even if there was it should be out of focus. Are you seeing this through the viewfinder of your camera (or LCD display), or when you look through the lens (detached from the camera)? If you do not see it with another lens on the LCD display, then the problem is with this new lens. If you do see it with other lenses, then possibly dirt on the camera's sensor. In either case, try to exchange the product.

I've not noticed any scratching. A hard plastic part of the frame rests on the front of your lense and a soft plastic coated wire rests on the back of your lense.

is the polish a protector? I was hoping for a few years not months...after all the car is 16 years old and this is the first time i need to do them and they are not that bad, kind of like the beginning. My lens are not yellow in anyway, just dull. Looking forward to "new lens".

Somewhere around the 4 mark. It's such a great lens. I don't think you'll regret purchasing it, truly.

I smacked mine a couple of times on the side of the lens took an air can and blew in all the cracks and crevices, Put electronic endust on a lens cleaning tissue and forcefully pulled the telephoto lens out gently while pushing on the extension button and wiped it all clean several times. Even ran the tissue a ways into the crevice surrounding the lens. Somehow it started working again which thrilled me since Ehow wanted $176 just to look at it if I would send it in. It still sounds a little scratchy but I will continue cleaning it every use. It sounds like it has a minute piece of sand or something in it. Hope this will work for you.

My D40 developed a blurry line in the middle of the viewfinder after about 2 months (or maybe it just took me 2 months to notice it). It doesn't affect the photos, just the viewfinder, but it is a little annoying at times. I'm guessing it's a warp or something like that in the focusing screen. Since I take most of my photos in the Summer and Fall, I don't want to part with it for another couple of months, but after that I plan on sending it in to Nikon to have them check it out while it's still under warranty. It really hasn't been a big deal, and the camera is great in spite of it, but I would like to make sure it's not going to get worse.

If there is condensation inside the lens there is a crack in the lens cover or a bad seal. I have not had any problems at all. The picture is clear and bright. You do have to keep the lens clean. Even works perfectly at night.

This should not have happened, possible threads crossed or put on too tight or put on when uv lens was warm then contracts when cool and locks. Best advice is go a reputable photo shop and they will help if all else fails.

I also have the anti-glare coating on both inside and outside the lenses. This product was recommended by my optometrist for use with such coatings. After a year of daily use with microfiber and synthetic cleaning cloths, NO problems at all. Just make sure that the cloths are clean and the lenses don't have particles on it, otherwise they scratch the coatings.
