FAQs—Pontiac Bumper Cover
- I found some scratches on the bumper cover of my Pontiac. How can I fix the slight damage on the paintwork since I don’t have time to paint the whole bumper cover? What can be a good solution here?
The scratches on the bumper cover can be fixed through sanding and touch-up paint. First, check the severity and size of the scratches. If the nicks are over an inch in size, use 200-grit sandpaper. For smaller scratches, you may sand them using 400-grit sandpaper. After sanding, clean the area with damp cloth and let it dry. You can now apply touch-up paint starting with the inner parts of the damaged portions until the scratched areas are covered. Make sure that you don’t to go over the lines. Be careful in applying touch-up paint.
- I just found out that my Pontiac bumper cover has small cuts. How can I patch up these small cuts on a plastic cover?
Adhesion promoter can be a good solution for fixing small tears or cuts on a plastic bumper cover. Spray or wipe the cracks with the adhesion promoter, and then use a mesh patch. After this, you may add some epoxy adhesive to mend the tears. Allow the adhesive mix to harden. Fix the tears starting from the back and onto the front. Make sure that the filler/adhesive mix is applied evenly. The area should then be sanded to remove the rough spots.
- I used some adhesive mix and filler to cover up the small tears and cracks on the bumper cover. However, I think I sanded the area way too much, resulting in some low spots. What can I do to fix this?
You need to re-apply some adhesion promoter and adhesive mix. Add another layer until the surface is even and smooth. If there are pin holes, use plastic finishing putty or filler.
- I will be painting my bumper cover. What’s a good way to prep up the surface of the raw plastic cover? I want the coat of primer and paint to look smooth and even.
To remove dirt and oil, you have to scrub the surface with wax/grease remover. You may also have to do some sanding to make the surface smooth and even. By removing dirt and keeping the surface smooth, you can avoid bumps and rough spots in the paint. It will also help if you use some sealer before applying a coat of primer and paint on the bumper cover.
- I just painted my Pontiac bumper cover a couple of days ago. After washing the car, I found some runs and small bumps in the paint job. How can I even these out and make the paint work look and feel smooth?
To even out the bumps in the paint, you can sand these out with 600-grit sandpaper and water before switching to 1,200-grit sandpaper and water. The cover must be rinsed thoroughly and allowed to dry completely. Apply some rubbing compound after this; you may use a polisher or microfiber cloth. To make the paint smooth, you have to buff the area.
- What’s a great way to prepare the damaged bumper cover for repair? For plastic, what would be a good way to clean up the surface, including the edges and sides? I need some tips.
The gritty or grainy parts or surfaces have to be washed with soap and water. Lacquer thinner may also be applied on caked-on dirt or stuck grime that’s hard to get rid of. To remove dirt and contaminants around the edges and the sides, you may scrub the area with plastic solvent or plastic surface cleaner. This is a good way to clean up the part that will eventually be subjected to sanding and grinding, among other things. The bumper cover has to be cleaned up again after sanding and grinding and before applying any solution for the cuts and cracks.
- I saw some slight dents on the bumper cover. Can I easily pull the dents using a suction cup and plunger?
This technique is used by some DIYers, and this works for some. If this fails, what you can do is use a dent puller instead. Drill a hole right at the dent’s middle part. You have to put in the end of the dent puller through the hole you’ve drilled to pull the dent. To cover up the hole, you must use auto body filler after sanding the drilled surface. Then, let the filler dry fully. Once the filler is already hard, you have to even out the rough parts by sanding the surface again. After this, you can now apply a coat of primer and paint.
