Headlight Lense Repair Question

[supramann]

My headlight lenses on my wife’s Toyota are real dull & cloudy. I thought about replacing them but now I see that there are some restoration kits available. Has anybody tried anything like this? Does it really work? Here’s a couple I was looking at: http://www.autobodytoolmart.com/3m-h...8-p-16386.aspx and http://www.autobodytoolmart.com/symt...0-p-16214.aspx

Thanks
