Looks like water or something how can i fix it

 

is that inside or out?

 

meguiar's plastic polish.

polish away with a nice clean microfiber towel.

if it doesn't come out, then it's the inside.

wow, not only can some not search, they can not scroll either

 

if the plastic polish has no effect, its on the inside which means you have either a small crack somewhere or a bad seal.

If it does have an effect but you are not satisifed, recommend take it to a detailing or body shop and have them buff it out.

I had a crack in my passenger side from a very slight fender bender. I pulled the lens off (after heating), got the water out, wiped down the inside of the lens and sealed the crack from the inside with RTV and it worked great.

 

I am a professional detailer - I'll chime in.

When I bought my Z a few months ago I noticed this too. I too used the Meguiars plastic polish, however being the neat-freak I am, and how careful I can be, I used a power polisher.

I don't recommend using one because an inexperienced person can burn a hole right through. I used a 3000 grit polish with a 100% lamb wool pad then a resin-based glaze with a 9000 grit foam pad to finish it off.

Lens look 100%. I also did this the the dulled tail lights.

 

Maybe you meant haziness?
