I recently got a new BMW 1 Series 116D (2016) on a 4 year PCP deal. A week in, I've managed to scratch the bumper.

BMW 1 Series 116 D (2016) bumper scratch

Although it's a minor dink, I don't want there to be any risk of it devaluing the car for when I eventually trade it in.

Would you recommend repairing this myself or should I go back to the BMW dealership? What would be the price difference in the two and how would I go about doing a DIY job?

  • Is this just regular white paint? Not the flat paint BMW is providing on some cars? – Pᴀᴜʟsᴛᴇʀ2 Apr 10 '16 at 16:54
  • Do you mean matte paint? If so, then no, it's just standard. We do have the Supergard Guarantee if that makes a difference? – Sam Apr 10 '16 at 17:04

    I'd wait for our resident "body guy" to come on here (@JonathanMusso), but my gut check is, this is something you could fix yourself. – Pᴀᴜʟsᴛᴇʀ2 Apr 10 '16 at 17:09

It will most certainly be more expensive if you get a professional to repair this bumper for you. However, it will be a safe investment on your trade-in if it is restored professionally. We cannot discuss price on this platform, but, the cost to do this yourself versus taking it to reputable shop will be substantial.

If you decide to do this on your own, it is optimal to remove the bumper from the vehicle. I do not know how far the damage travels, I would suggest repainting the full bumper. Blending is not easily accomplished for someone with no experience. Add incorrect paint to the equation, the wrong amount of coats, etc, it will never look the same as a factory job.

You will need to acquire the paint code, which is located in your door jam, or sometimes in the glove box on newer vehicles. Take this to your local body shop supplier and get the matching OEM paint.

If you have no experience sanding, I would recommend block sanding the bumper instead of using air tools.. You could start with something like 500 grit sandpaper. The areas with the dents or major gouges, cleanup with 80-120 grit. Once sanded, wipe the bumper down with a cleaning solvent such as Final Wipe. Cleanliness and temperature is key with bodywork. You want to paint in at least 20'C temperatures without high humidity. If it is too cold, the paint will sink.

You can apply Bondo to the scarred areas. When applying Bondo, or any material for the matter, ensure that your trowel is clean and has no damage. If it does, this will leave streaks, pits, etc, all things you do not want. If there are any streaks you can use a cheese style grader on them once the material has tacked up a bit.

Sand it down once again, this time you could use 220 or something similar. Once it is to your liking you can prime the areas in question, or the whole bumper. Before doing so, make sure you clean the bumper with the correct solvent and then a tack cloth before shooting any material out of your gun.

Once primed, you need to sand again before your paint goes on. Sand it with 500-600 until everything looks dull. Clean it once again and you are ready to shoot your paint. Read the instructions carefully, flash times are different depending on the materials you get. You can ask the dealer how many coats of paint and clear was used on this vehicle. Try to match it.

Shoot your paint and the required amount of coats, and then your clear. It should dry at least for 24 hours. You can look at cutting and buffing the bumper once completed.

  • If you end up doing this and require further assistance, feel free to post more specific questions. – Jonathan Musso Apr 12 '16 at 16:05
  • Thanks mate. I think I'll take it to a specialist. Sounds very involved and I have absolutely no experience. Would it do any further damage to the paint work if I left it for a while? – Sam Apr 12 '16 at 16:06
  • No worries. Is it a plastic bumper? If it is steel then it is hard to say, if it rains, it can rust. If you do more damage to it, etc. You should be fine for a few months, no doubt. – Jonathan Musso Apr 12 '16 at 16:19
  • It's a plastic bumper, so I'm guessing it should be fine? – Sam Apr 12 '16 at 16:20
  • Yeah you will be fine for a while, just don't smash it again! :) – Jonathan Musso Apr 12 '16 at 16:22
