Re-glue facelift headlight?
 
I've been debating whether or not to bake my headlights in order to get some nice AE's in there. My only concern is that I've heard mixed things about re-sealing the headlight and don't want to have them fog up or catch moisture. For anyone who has done it successfully what sealant did you use?

I've never done it, but it seems to me you don't need to add anything if you don't scrape anything off... use a heat gun in stead of baking.
heat it up again when install and press hard enough to gain a complete contact on all sides... shouldn't have any problems if done properly.

So just re-use the adhesive already there? That's where my concern is because it's 7 years old and I imagine anytime you rip apart adhesive it's best to clean it up and re-seal (aquariums, furniture, windows etc)

you're heating it up to a point that the glue particles split.. so technically if you heat it up to the same temperature once ready to glue back together, it will bind the way it was originally. just make sure you do it thoroughly.

if you are seriously worried, use silicone, but that will get messy if you need to go back in.

Facelift sedan yes, not a coupe...

How did you re-seal your headlight and did it hold up?

facelift coupes are the only ones that you have to bake. I have not done it, and I am hesitant to even try because of the moisture. I think you are right, something that is ~8 years old I would think you should clean re-glue/epoxy/seal the head light. even if you reheat it to the same temp as previously stated, you will not have the same bond because you have broken that bond down through heat and separation (particles that once held together will not all hold the same as they did on the first seal)

Other option - drop the money and get the depo's with AE's. ~500 to 700 and from what I have read, the quality is no where near the quality of OEM. Loose loose.

My 330 will continue with the OEM, as there is a lot better things I could spend 500 on before lights.

When I installed my AE's into my facelift headlights I had to bake them. They came apart very easily. I disconnected the headlight and ballast obviously. As far as putting it back together, I just put the two halves in the oven for a few mins, then squeezed them together with a towel and some tape for a few more mins until the glue hardened. I went through an entire year like that, never had a single problem and never fogged up.

did you put them on a year ago or did something go wrong? im also interested in putting AE's into my '04 Coupe im just too worried about something going wrong in the future

Sedans have clips

I've done it on a set of e39 headlights which are the same process. I just ran a line of silicone within the grove of the old sealant, reheated with the heat gun and applied the lenses. Since I've did them there has been no fogging, moisture, no issues.

WheyArea 12-27-2012 02:44 PM

Ok I'm convinced. I'm gonna order some AE's and do it next week. Any suggestion on lights?

When I did this on my facelift sedan I didn't bake or resell anything so far so well like 3~4 months

|2eckLesS 12-27-2012 03:02 PM

Because facelift sedans have clips no need to bake. Ill be watching and waiting and might tackle this as well. I just hate to put my nice headlights in an oven....

Put them on a year ago and took the headlights out and sold them working perfectly fine. I upgraded to the Umnitza P46 FX-R, LED, AE, HID setup..

The heat will not do anything to your lights so as long as you follow the recommended procedure. 150* for 15 mins or so. All that will do is soften up the glue, it will not deform any plastic what so ever.

How do you compare the Umnitza HID's vs OEM?
