Best way to seal tail lights? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Dman II-40 · 10-13-2009, 03:08 PM

So it is raining really bad in CA right now. When I get out of class I go to my car and find a nice 3 inches of water in my spare tire compartment!!! I located the leak at the passenger side tail light seal. I cleaned off both surfaces, now I need to re-seal it.

What is the best product to use? (I want it to stay tacky like the original, not harden like M3 window weld.)

Butyl tape

Bushido · 10-13-2009, 03:26 PM

^ you can get it at a dealership

nothix · 10-13-2009, 03:29 PM

you can buy new sealing pads from courtesy parts, or just use silicone

Great stuff, but very hard to remove in winter and messy to deal with in summer.

What they all said. OE butyl rubber, about $12 a roll.

Dman II-40 · 10-13-2009, 04:12 PM

I'm at a pepboys and just went to autozone and they never heard of the stuff (generally they don't know shit anyway).

ayuaddict · 10-13-2009, 04:14 PM

how about good old RTV or something similar?

easy to cut with a razor if necessary, seals well if left alone.

why would you want that gorilla jizz that comes stock?

Tom25666 · 10-13-2009, 04:27 PM

yep, i used buytl at first and it kept leaking so i used some clear silicone and no more problem.

***S14DB*** · 10-13-2009, 04:32 PM

Nissan's sealing tape is the best in the industry. I would just buy some instead of trying to reinvent the wheel

g6civcx · 10-13-2009, 04:33 PM

$20 of buty tape from the dealer is enough to do 2 cars and still have leftover.

TommyGun · 10-13-2009, 05:14 PM

just sealed up my friends te72's tails last night with some stuff from monument (they're in a couple spots around the bay area) ill axk him how it held up

Dman II-40 · 10-13-2009, 05:24 PM

I ended up getting this stuff it is a 3M product. It is 1ft long strips of caulk that doesn't dry. We will see if it works. I called the dealership and they would have to order it.

singlecamslam · 10-13-2009, 05:36 PM

i used window sealent, works like a charm. Probably never gonna get the tailights off now. You can also use strip caulk, they sell them at paint stores.

same here, i went with a window sealant,
look on the back what is in it and it says butyl something,
i got it at autozone.

black stuff rolled up,
too bad dealer didnt have it.
and it came out to be like 12 ish.

Dman II-40 · 10-13-2009, 07:51 PM

Yea i just got that strip caulk. Tested it with a couple cups full of water and it looked like it worked. If it fails on me I will just get the OE thing ordered. Now just have to let my trunk dry out. Thank for your help guys, greatly appreciated.

Spring Break '92 · 10-13-2009, 11:16 PM

I had used some black windshield silicone on the inside of the car, which I don't recommend. I actually still had the tails leak too. Fail. i have different tails now though.

zenki.life · 10-14-2009, 03:15 AM

yep everyone has answer correctly

Enna · 10-14-2009, 07:54 AM

I could've sworn this thread said "best way to steal tail lights?".

rican_nick · 10-14-2009, 08:41 AM

Nissan PN's for butyl...clean everything up nicely before installing or it can leak ..obviously.

OMG, thank you for the picture!!!

saved me so much time to look for the part number/explain to the ppl at the dealer...

*hOngsterr* · 10-14-2009, 08:06 PM

haha when i installed my koukis, and since it was raining i checked if my hatch was still leaking and it was.
i went crazy cause i packed that shit into the tails and cleaned them clean!.

then with a bucket of water i found out where it was leaking from,
the weather stripping lol. pulled it out and saw this lil crack and i just used some leftover sealant and packed it all up again =]

so im good now

MR209 · 03-01-2017, 12:45 PM

Since it's been 7.5 years, I figured I would post for an update on how the different sealants are working for you guys. The tail-lights on my hatch are still leaking after installing new tail-lights that included foam strips pre-adhesed to the lights.
I just got off the phone with Central Valley Nissan in Modesto and they wanted "43.95 a piece" for a roll of B6553-89915. Courtesy Nissan's website lists 43.69.
I looked it up on Fontana Nissan's website and they want 34.95, so that is a much better price.
What do you guys think about using the OEM roll of Butyl Sealer vs Mortite vs Black RTV vs just shooting a tube of window caulking between the tail lights and body when installing?(Probably not the last two options).
I am going to check out Lowes and see if they have rolls of "Mortite" Weatherstrip and Caulking Cord. http://www.frostking.com/mortite-caulking-cord/

I would ultimately like to find a roll of Butyl Sealer from Oreilly's/Autozone like hOngsterr did, but I tried Oreilly's and they didn't have anything other than a roll of foam weatherstrip. Next I will try AutoZone.
