If you have had your vehicle for several years or have recently bought an older model, you might discover that the window trim on the side windows is starting to crack and rot. That’s definitely not a good thing since it is eventually going to disintegrate completely, implying your window won’t close properly and the rain and wind will sip into the car. Under these circumstances, it’s best to change the trim completely. You can take it into a glass shop and have them do the work if you wish. However, this is a kind of project you can handle, letting you to save your money for other things.
Step 1 – Take the Old Trim Out
Roll the window all the way down. Next, start prying off the old trim using a flat head screwdriver. Depending on how old the trim is, it should come off fairly easily in long strips. Work your way gradually around the window until you have removed as much of the trim as possible. You’ll often need to work from a number of different angles. Make sure to get off as much of the adhesive holding on the trim as possible.
Step 2 – Scrape
Using the small metal scraper, move all around the window to remove the rest of the adhesive and any of the rubber trim you could not get off with the screwdriver. Go slowly and scrape as hard as you can, but ensure only to scrape the area where there was trim and adhesive, otherwise you’ll mark the paintwork. Using masking tape as a barrier can help keep damage to paintwork.
Step 3 – Sand
Use sandpaper to scour the area beneath the adhesive and trim, making sure you get rid of any particles that remain. This is vital since the sanded metal will give a better surface for the new adhesive. Use a coarse-textured sandpaper to go all the way to the metal. When you’ve completed these, clean the surface with a damp rag and let the metal to dry thoroughly. Gently brush a small amount of primer over any bare metal to stop rusting at a later date.
Step 4 – Fit New Trim
Before you actually begin to fit the new trim, you need to measure the sides of the window and cut the trim to size if it comes in large lengths. If you’re not sure about your measurements, allow a little extra since you can trim it back later. Use a very sharp knife for cutting and where you have 90-degree angles, cut each strip to 45 degrees so they fit closely and cleanly against each other.
Next, spray the inside of each piece of trim with the spray adhesive. You only require a light coating so it doesn’t drip. Make sure that you spray the rubber and not the appropriate area of the car door. Spray and fit the pieces one at a time, ensuring they fit well against each other and that the trim is firmly in the door. As you put each piece in position, hold it there for several seconds for the adhesive to take hold.
When all the pieces are fully put into place, allow them to dry for a few hours before rolling up the window again. Repeat same for the other windows.
