hey followed this technique (almost) mine weren't that bad just the tops mostly that is next to the hood.

looks like brand new. nice good write up.

 

my headlights were fogged up also. and an easy way i found out to defog them is to take plastic polish and use that on them... it works great

 

Yes this saves money from buying headlights, My dad & I do this as a local self advertised business on the side. Get a good buffer (snap-on or so). We found "meguires" professional cleaner & polish at Oreilly's, one in a white bottle (thats the first one to use) then a blue bottle. a bit pricey, $18 for both, but great stuff & it lasts many cleanings/cars. Once sanded, polish in the cleaner & you will see the difference, then use use the blue bottle/polish. Plus you can see better at night.
