i have a red 2000 Honda Prelude my baby...........and the left headlight is getting fogged up on the outside..how can i remove that fogginess????

 

in order of aggressiveness u can do the following

very unaggressive: plastic polish
more aggressive : regular polish
more aggressive : rubbing compound
even more aggressive: wetsand

If its not pitted, you don't need to wetsand.
if it is, and that irritates you, as it does me, you can get a headlight repair kit from most large retail department store chains.
Like walmart or Meijer's, I don't know how many states Meijer's is in, but they're like walmart, but not as dirty. at least here anyway.

but I got a little kit from a Meijer's here, and it has all the sand paper you need, and some really crappy plastic polish. just get some Meg's PlastX instead. I used some 3M liquid rubbing compound before I finished it with the plastiX and the finish came out great!
If you use PlastX you really shouldn't be able to mess anything up.
if you wetsand, make sure you keep it wet, otherwise its dry sanding. Damp doesn't count. Use a hose. Imagine having sex with your jeans on, zipped and buttoned. Ouch. Keep it lubed or leave it alone.
