Product Details

Protection: Is priceless! When you're putting together a set of high-end headlights, the last thing you want is moisture in 'em the first time it rains outside. After many years sealing headlights with spools of butyl meant for windshields and sunroofs; we've finally got a product that puts OEM-style sealant designed specifically for use in headlights, and indeed it works well!

Purpose: Until now, the only other butyl-ropes on the market were meant for "universal" applications, and true headlight butyl only came in blocks that were nearly impossible to apply without industrial machinery. Morimoto's Retro-Rubber is designed specifically for resealing headlights, not windshields, sunroofs, etc.

Consistency: At room temperature, the RetroRubber has a much harder consistency compared to OCI Butyl glue. Given the "fingernail test" it will harden up just like any OEM Butyl Rubber glue once cooled.

Color: Not all headlights are created equally! Whether your housing was originally sealed with black or gray glue, the RetroRubber has you covered with options. Available guessed it, black or gray... you won't have to settle for a mis-match.

Quantity: Each roll comes with approximately 4M of glue, which is easily enough to re-seal two or more large headlights. Simply stretch it out until it's the perfect thickness to fit inside the headlight channel, cut it to length, rough-fit the lens back onto the housing, heat for at 265F for seven minutes, and compress the housing back together. Done!

Best Decision Ever

Gregory Morgan Reviewed: 04.23.2019

Bought this glue Feb 2019, due to my headlights where keeping water like a bucket. Since the closure of the headlights not a single drop of water or moisture seen. Great stuff gonna order 2 more for my friends who want to retro there headlights.

Great quality

I prefer the black color but they both work the same and used both. I prefer the black as it looks cleaner if you manage to get most of the grey out from the stock assembly.

OEM notch stuff!!

David W. Darling Reviewed: 09.15.2016

This stuff is amazing! Very easy to work with...looks and seals just like oem, if not better!! Looks like a professional job. At first I was concerned about having enough to seal both lights but I had plenty and probably enough left over to do one more light. I am so thankful that someone recommended this stuff to me. It's made me a regular customer for other things as well.

beware of hot days

Randall Reviewed: 08.30.2016

the stuff matched the factory sealant to a tee and seals out water like no other. Just make sure u get all the old sealant or as much as u can off the old housing don't over do it! or you will have dripping sealant on your beautiful new projectors and inside housing and having to take them all apart again, clean up the mess and resealing them..(hoping that this time they seal out the water and NOT drip on the inside again)

Great sealant

The retrorubber butyl glue is a must with any retrofit project. It works perfect. I have sealed up two sets of headlights so far and still have enough to seal up maybe one more light. Both sets of headlights have had zero moisture issues!

This stuff rocks!

trent Reviewed: 06.24.2015

Have heard stories about moisture problems after people finish up a retro. Being my first project I didn't want to have the hassle of fogged lights. Nor the mess of standard butyl. This stuff was great to work with. About 6 weeks later after heavy rains and lovely St. Louis humidity my lights are clear as can be.

Best way to seal your headlights.

Chad Reviewed: 06.24.2015

To me this is the best way to reseal your lights. This is a much better option than using any glue out of a tube. It is more controllable and can be cut to the perfect length needed. No waste! Seals perfect once headed, and there's plenty of it to do more than a set of lights in one roll. I will be buying it again for my next project.

What a difference

Nicholas Reviewed: 05.18.2015

Went from using 3M window weld to TRS Butyl and the difference in night and day. Easier to work with, not as tacky at room temp, little stiffer than the 3M but makes a MUCH better seal on the headlight. Cannot pull the lens off the housing after it cools like with the 3M.
