How to Glue Automotive Weatherstrip the Right Way

Weatherstripping is not a fun or sexy part of auto restoration but adds a lot to the look and functionality of your vehicle! Using quality products and installing them properly can ensure that your interior is protected from the elements, that your vehicle looks good and you have a nice quiet ride for many years to come (no window rattles or air noise).

When installing weatherstripping, most people lay a thick bead of adhesive down on the metal and push the weatherstrip right now on top of it. Glue oozes out the sides and the weatherstrip can slide out of place not to mention it will take hours to dry! This is a simple way, but not the best way. At Steele, we pride ourselves on doing the job right the first time so let us show you how!

To do the job right, you’ll only need weatherstrip adhesive (we recommend 3m Super Weatherstrip Adhesive in black), a popsicle stick, and the weatherstripping you need to install. Gloves are nice, but totally optional.

We also recommend you do a thorough job removing the old weatherstripping and cleaning the gluing surface properly.

Start by applying a very thin bead of adhesive directly to the metal (less is more), spread it out with a popsicle stick to make it into a thin film and let it dry a few minutes until its tacky.



Next put a thin bead of the adhesive onto the weatherstrip itself and spread it on to make a thin film and let that dry until slightly tacky (should only take a minute or 2).



Once both sides are tacky, put one last thin bead of adhesive on one of the surfaces and spread it out with the popsicle stick. Next, lay the weatherstrip down on top of the adhesive on the vehicle, pressing firmly over the weatherstrip to make sure full contact is made with the metal.  Since you’re only using a little bit of adhesive it won’t gush out the sides and will dry much quicker too. In fact, it sticks where you lay it pretty much instantly! (This picture shows a weatherstip stuck down just seconds ago holding up a 3lb piece of Aluminum!)



Allow the adhesive to cure for a full 24 hours and the job is done!


For our Peel and Stick products (great for fiberglass bodies, by the way) installation is a breeze! All you have to do is peel the backing off and stick it down. But don’t forget, just like when using adhesive, prepping the metal gluing surface is very important so don’t skip that step! Also- this stuff is extremely sticky so you only get one chance to stick it down. We recommend that you lay everything out before you get started to plan right where your weatherstripping needs to be so there are no surprises and all parts line up as they should.
