I have had my Honda for just over 6 years now and I noticed that the headlights were getting a bit foggy, but they still worked so I just let it go. I was at the auto parts store a while back and picked up "headlight defogger" but it was so cold out I wanted to wait to try it in the nicer weather. (Honestly, I forgot I had it until a week ago. lol) I put it on last weekend and to my disappointment it didn't work. Of course, I can't return it because it's been too long now and I can't find the receipt.

A friend of mine mentioned to me that I needed to get my headlights fixed and I told him my story about the goo that didn't work he suggested bug spray. I'll admit I looked at him funny, but tried it this past weekend.

I hear that it doesn't last for a long time and I have no idea why it works, but it did and that's all I care about!
