Hazy front emblem

[giorgoXXI]

Hi,

The Lexus emblem in the front grill is looking very hazy, I don't if any of you guys have encountered this issue. I've tried cleaning it off but it seems impossible.

Since the IS-F has PCS, the emblem is really expensive because I think it houses the sensors.

Any ideas how to clean it?

Thanks

Have you tried a plastic polish like Novus ?

I'd be surprised if the emblem contained the sensor, usually it's simply a shield protecting the sensor behind.

If it is plastic then I achieved a great result with fine cutting compound on a microfibre cloth. 

After my tailgate was repainted the badge looked misty and 5 minutes work with meguirs cutting compound had it looking brand new.

The badge simply allows the sensor to pass signals through it. The sensor itself is behind the grill. Doesn't explain why the badge is £500 but there you go.

as @PhoeNicks suggests the sensor is in its own cradle mounted under the bonnet slam panel and a good few inches back from the badge. I was interested to check this out on the ISF that was at the breakers near me a couple weeks ago. Having just looked at my badge it might benefit from a bit of a polish up too.

Thanks for the replies.

I did try cleaning it off with Meguiars PlastX and got nowhere. It did work for headlights but not for the emblem. Maybe I need to try harder! It did look clean initially but within a minute it would become cloudy again. Is there anything better than Meguiars? Would I have a better chance with the Novus polisher?

If the emblem has no sensors then I don't understand why it is so expensive. The emblem for non-PCS cars is around £50.

It is rather odd... its probably over engineered in some way for what looks like a bit of plastic. I tried to source one in the states when I was doing a front end refresh... Still the guts of £400 and that was before shipping. Mine is still like new so I didn't bother in the end.

Must be special radar transparent plastic...

I have an aftermarket better looking badge. It did say not suitable for cars designed for people who rely on technology too much ;)

I just used good old fashioned machine cutting compound and a coat of chemical guys 'blacklight' nano sealer.

So I gave Meguiars PlastX another try, this time spent almost 30 minutes going through the emblem and the results are better but not perfect. I don't know if the improvement is going to last either, the plastic probably needs to be coated to protect it I'm thinking. See pictures below of before and after:

Try some headlight polish, if the badge is like that I suspect the headlights could do with a touch up too. Just use a good wax to protect it, and give it more shine.

A tip from the plastic model world

If you can take it off, dip it in this stuff: http://www.scalemodelguide.com/hints-tips/general/using-klear-floor-varnish/

. There are plenty of online tutorials of how to get a good finish

Is it radar transparent?

[MNMJ]

Good question. I'll build a model of a stealth bomber, give it a coat of Klear and then see if it shows up on radar
