Not sure if this is the right spot to post this. 3 times now I've used RTV silicone to reseal my headlights. They fog up every time. What in the hell can I use to keep them from fogging up. I'm very pissed with cobalt headlights at this point. What can I use that's easy to find and works good? Please help me!!

 

Get any moisture out and then use windshield urethane maybe? Don't know how it would bond to plastic though.

 

U don't want the headlights 100% sealed or u
Will always have fogging with any temp change

 

I believe the headlights are vented, and perhaps the vents are blocked

 

I've been looking to do a retrofit myself and have seen this glue recommended elsewhere:

OCI Butyl Rubber Glue - Accessories from The Retrofit Source Inc

 

The headlights are infact vented and not sealed 100% from factory anyways as in the back where the bulbs goes in there should b a hole in the rubber gasket

 

You want to use this.

 

Yup butyl base is amazing that's the only thing I ever use

 

As others have said, if you are completely sealed, you will have fogging problems.

Easiest way to fix it is just drill a tiny hole on the bottom side of the light.

 

i used RTV silicone rubber. sealed up nice. the headlight always vented thru the back though where you secure the bulb at.

 

they need to be vented HOWEVER even factory headlights fog up and haze. my are a perfect example. the butyl stuff is the best to use. restrofit source sells it cheap .

 

i usually use 'GOOP Automotive' good stuff.

 

I used the original butyl just heat up press back together, then a too layer of automotive goop
Flows out nicely
