Seal Your Car from Harsh Weather: Changing a Window Trim
Over time, the weatherstrip seals, also called the window trim, installed in your car windows may harden and start to crack. This can lead to punctures and pave the way for water and other contaminants to enter your car. When you discover that the window trim has started to wear out, what you should do is replace it as soon as possible.
Difficulty level: Moderate
Tools you will need:
- Sharp knife
- Coarse sandpaper
- Flat-head screwdriver
- Damp rag
- Metal scraper
- Spray-on adhesive
- Measuring tape
- Car primer
- Masking tape
Step 1: Start taking out the old trim by rolling the window all the way down. Use a flat-head screwdriver to pry off the old, damaged trim. The window weatherstripping should come off easily and in long strips, depending on how damaged they are. If they are too brittle already, then you may spend more time removing them, as they can break into smaller pieces when you pry them out.
Step 2: Continue prying the window trim from various angles, and ensure that you remove as much of the old trim's adhesive as possible.
Step 3: Get the metal scraper and use it to remove the remaining adhesive and any of the rubber seals that you couldn't get rid of using the screwdriver. Scrape as hard as you can, but do it slowly as you wouldn't want to mar your car's paintwork. Alternatively, you can also use a masking tape as a cover to avoid damaging the paintwork.
Step 4: Get the coarse sandpaper and scrub the area beneath the adhesive and trim. You'll see afterwards that the sanded surface will provide for a better metal surface, enhancing the stickiness of the new adhesive.
Step 5: After completely sanding the metal surface, use a damp rag to gently spread an ample amount of primer over the exposed metal to protect it from corrosion and prolong its lifespan.
Step 6: Get the measurements of your car window's side. Cut the window trim according to your window's specifications, if necessary. But if you're not sure of the trim size, then add a little extra to your measurements since this can be easily trimmed later on.
Step 7: Cut the trim using a sharp knife angled at 90 degrees. Cut each of the window seals to 45 degrees so that they fit snugly and accurately against each other.
Step 8: Spray the inner part of each piece of window trim with some spray adhesive. Add just a thin coating, so that the adhesive won't drip to unwanted areas of your car. Make sure that you spray the adhesive only on the rubber, and not on the surface of the car window. Spray on the trims one at a time.
Step 9: Hold the trim in place for a few seconds after installing it to ensure that the adhesive has taken hold already. When you have sprayed on all of the pieces of trim and placed them neatly around the window, leave them for a couple of hours to dry before you roll up the window again. Repeat the same process for the remaining car windows.
