Hi Joe.
Not ignoring you. We are in the middle of a cold snap with very cold temps right now. The Zed is parked in an unheated garage with a trickle charger. If there was going to be any problems with the hole fills I'm sure it would have happened by now. When it gets above freezing, I'll take a close look for yah. As you might have seen, for my repairs, I tried to used as much 'doner' material as possible, and minimize any filler to contour use. I got the doner from a local Ford Dealer on a Sunday when I had my choice from the dumpster. The reflector ports were almost totally filled by filing two opposite bevels on the repair disk. They just popped in, and with an additional chamfer for adhesive and fill actually worked better than I expected. The washer ports - Well they are supported by a hard plastic nozzle bracket. If you look to can see that there is an opportunity to slip in repair mesh between the bumper and this hard plastic. That's what I did. Then filled the port with doner material before the final contour coat of filler. Just a coupla tips ... Ill do my Spring inspection soon I hope |

Hi BJoe
I wasn't ignoring you. I was just waiting for Spring to return allowing me to do a proper evaluation over one winter season. The Zed spent most of its time in an unheated garage. My hole fills showed no signs of cracking. I think by using a doner bumper to provide filler material similar to the Zed Bumper, that stress cracks are avoided. Plus the expanded metal mesh heps in supporting any adhesive / filler you need to apply. Good luck with your project. |

The bumper repair kit you can buy from any Napa store includes several fillers and adhesives. I tried to limit the use of filler by using donor bumper plastic when possible. Plus there are self adhesive wire mesh patches available for additional support.
My bumper shows no cracking of the repairs, except where I have scuffed the fangs on driveway approaches |

I have had no issues with the bumper and filler after 4 years. And that includes Canadian seasonal temperature swings and two extended tours totalling 4000 kms.
No cracks or splits and I admit two misadventures with curbs which gave the fangs a significant whack requiring cosmetic fill and refinish (only the fangs). So that means the bumper repairs have performed without flaw. Cheers |

Someone needs to make a thin carbon fiber fang cover that slips over the damaged fang and bolts on from the underneath. I think they would sell like hotcakes

Nice work, Hedward. Did you use the Bondo epoxy filler or go with something different? My car is in the shot for vanos work, but once I get it back, I really need to touch up my fangs. BTW, I like the M stripes on white. Looks good.

I'm currently in the process of repairing the fangs on my Z4 MR and I'm having a hard time creating a hard edge on the leading corners.
I'm using the Bondo Dent Repair Kit which includes a can of Bondo Auto Repair Filler with Red Cream hardener, Bondo Glazing and Spot Putty, a spatula, various grit sandpaper, and a can of primer. Every time I build up the corners and the front edge, when I sand it gets rounded off. I'm tempted just to get it to look pretty much the same on each side and call it a day. Last year I had to get the bumper repaired because someone apparently tapped me in a parking lot and cracked the "septum" between the two kidney grilles. (Mixed anatomy references I know, but you know what I mean!) The shop suggested painting the lower fangs flat black so that it would be easy to repaint scratches, so the painting part will be easy and it will won't be as visible as if it were painted body color (Interlagos Blue). For anyone that's done this, any tips on getting a sharper edge? Also the under-engine tray has gotten banged up and there's a hole in one of the molded corners that are a few inches back from the front edge. That part's now $400 so I'm going to try and repair it with a Bondo Fiberglass Repair Kit. Has anyone used this before on this type of plastic?

As far as retaining the sharp edge on the fang could you possibly attach a piece of sheet metal to the underside which sticks out a bit to create a shelf. This may prevent rounding the edge while sanding.

"- bumper repair epoxyThe question has been asked but no one has pointed to a specific product. I watched a bunch of videos on YouTube and then went to O'Reilly's and got the Bondo Dent Repair Kit, which included a can of Body Filler, which is what everyone in the videos seemed to be using. You mix a golf ball size glob of filler with a 1.5" strip of Red Creme. You fill in the area and then sand it down. But apparently this isn't the stuff that should be used to repair the fangs. So I went back to O'Reilly's after Googling bumper repair epoxy and discovered that they also had this product, which is also described as a bumper repair epoxy: So if this is the right stuff, I'll try it tomorrow. Amazon also has products by J-B Weld and Permatex that appear to be similar. I have been building it up gradually and sanding between applications but I've been using hand-held sandpaper and a foam sanding block, so obviously this isn't working correctly. I'll try wrapping the sandpaper onto a paint stir stick and see if that works to get a sharper edge. Anyone have any ideas about my other idea of using a fiberglass repair kit to repair the holes and cracks in the underhood shield panel? Will fiberglass work to repair this type of plastic?

When posted, there was a pic of the Bondo epoxy similar to what you just posted, but the link went bad. I'll add your pic to the OP. But for a larger job, where more material is required just ask for it at a body shop repair supplier. It will be less expensive in larger quantities.

This is just what I needed, thank you for this DIY. My car is out of commission until I bulletproof the engine, but the front fangs have always annoyed me. I also would like to fill the holes from the front bumper bracket. If the results look anything as good as the results here, I'd be thrilled.
