Have some new taillights to put on my 200 and need some suggestions on what to use for a good sealer. I hated the sealer I used for the lights on my coupe so hoping someone has a good recommendation....

I scraped a bunch of original factory sealer off of the old tail lights and made a pile of it. Then I heated it up with a propane torch (or heat gun), and started to kneed it up. Then I rolled it into "snakes" (remember Play-doh?), and reused it. Worked great.

3M Window Weld butyl ribbon in 5/16" or 3/8"....Just did this a few weeks ago. A nice independant auto glass shop might even give it/sell it to you, but it's $20 for 15ft from the auto body places...Won't find it @ Lowes/etc...

The correct sealer is 3m strip caulk. it is identical to the OEM sealer. It worked great on my 200's taillights. You need to use multiple layers of strips to build it up thick enough.

nope sorry, there's just no way the "correct" stuff ahs to be run in multiple layers!!!

the 3M Window Weld in 5/16" is PERFECT. 1/4" works pretty well but the 5/16 is the best.

I agree, 5/16" Window Weld is just about perfect. Be sure to pinch it a little to give it a little extra "tallness" after you've laid it around the perimeter of the lens. Otherwise, you might not get a perfect seal between the body and the lens.

If I were to do it again, I would probably go with the 3/8" stuff to help ensure a good seal. But I haven't tried it, so I can't recommend it.

Huh? The Strip caulk comes in 12" long strips. Its a tar like stuff that never dries just like the OEM stuff. I just filled up the seal channel with enough to protrude some and then bolted it on. No leaks after lots of Oregon rain.y Once it gets squished down it becomes one blob. Window weld would work fine but wouldnt you have to clean off all the original stuff to get it to adhere? You dont have to worry about it with the strip caulk. Also wouldnt window weld make it a real PITA to remove the taillight if you ever wanted to?

:stupid: that's the right stuff and you can do all the tail lights. It's best to remove all the old stuff from the light and body and start new rather than tryin to patch in 1 spot. It's usually dried out and cracked anyway. Once you take the light off it will make a mess anyway as I'm you know already. I think brake clean will remove the leftovers/cling-ons from the light without damaging the light itself, but as long as there are no chunks, so you can lay the bead in flat it should be good.

Thanks for the tips guys. Luckily these lights were seemingly never mounted or only for a short time as there is no old sealer to clean off the lights, just off the car. Now if any of you have an extra trunk lock sitting around please let me know, doesn't need to work I just need to fill the void in the lights.
