For some vehicles, there are several plastic covers on the bumper. When you wrap it with vinyl wrap film, you can remove those covers first or leave them on. Here are some tips for both approaches. And you can make up your mind accordingly.
Remove the covers beforehand
When wrapping a bumper with a few plastic covers on, you can remove those covers straight away. You can then clean up the whole area thoroughly (including the main bumper area and the covers), especially the edges around the covers and on the covers, as dirt and moisture tend to build up there.
Next, you can take a small piece of vinyl wrap film to wrap the covers first. You do not need to wrap behind the covers. Just wrap enough to the edges to ensure full coverage. Form the material around evenly, seal all the edges, and re-install it back to the bumper.
You can then apply the vinyl wrap film to the bumper as usual. When everything is set and done, cut on the side of the main bumper area around the cover, and remove the excess material. Then, use your squeegee to seal all the edges. When doing this, you can add light heat to help soften the vinyl wrap film, especially if it is a thick one.
With the covers being removed and wrapped first, you get a higher chance of achieving a high-quality finish. You do not need to worry about making bad cuts when wrapping with the unwrapped covers. Otherwise, once you make a nasty cut in this situation, you might have to re-do the whole thing at some point.
Leave the covers on
If you choose to leave the covers on, you still need to clean everything thoroughly, including the edges around the covers. After the cleaning, add heat around those edges to make sure it is dry.
Then, apply the vinyl wrap film onto the bumper. Use the soft part of your squeegee to glide around the edges of the cover. Then, sharpen your blade, and cut along the side of the cover with a shallow blade. Be patient, and make sure your knife is running parallel to the side of the cover without touching the paint.
Once the cut is made, use the soft part of your squeegee to glide around the edges of the cover. Use the hard part of your squeegee to do it again, making sure the edges are sealed the material is formed evenly around. Double-check if the cut you made is clean and even. If not, use a sharp blade to clean up hackly cuts.
Last but not least, post-heat the area with your heat gun. There you have your perfect wrapped bumper. Learn more wrap tips at teckwrap.com
