Porsche 911 996 rear wiper delete

Here’s a revised version that sounds more professional, but still keeps it approachable and fun:

This is a rear wiper delete for the Porsche 996. Once the factory wiper and mechanism are removed, a large hole is left in the rear bodywork—this part is designed to neatly fill that gap.  I looked online to buy one, but $129 is just ludicrous! and I don't think it even looks that nice as it doesn't sit flush with the bodywork (not naming the company)

After printing, I wrapped the blank in automotive vinyl, trimming it to the lower lip so it’s retained by the body panel once installed. Avery Supreme Gloss Silver Metallic is an almost perfect match for Porsche Arctic Silver.

To remove the wiper arm, undo the 13 mm nut about 90% of the way. Then gently wiggle the arm to loosen it from the spline—this is the easiest way to free a stubborn wiper arm without it launching itself (or you) across the garage.

From inside the car, remove the rear interior panel that runs under the rear window by pulling it straight toward you; it’s held in place by sprung clips. This exposes the wiper mechanism bracket and wiring. The assembly is secured with three 10 mm nuts—remove these, unplug the wiring (including the relays), and lift the mechanism out.

With the mechanism removed, you’ll be left with a hole passing through both the inner metal skin and the outer body panel.

Apply your adhesive of choice around the lip of the blank (avoid silicone, as it can react with paint over time). Seam sealer works well e.g. tiger seal. I used black, as it gives the cleanest and most professional finish against silver paint.

Carefully feed the blank in from inside the car. This part is very fiddly—if you drop it between the panels, there’s no way to retrieve it. What helped me was wearing a glove and adding a small amount of adhesive to the back of the blank, which allowed me to guide it into place without it slipping off my finger. Good luck. Angle the blank so the two flat sides clear the inner skin first, then rotate and align it with the outer hole. Press firmly until the face sits flush with the outside bodywork.

i kept pressure on the blank from the inside as a second person wiped away excess sealant from the outside before it dried. This is definitely a two-person job—otherwise, you risk pushing the blank into the body, where it will be lost for all eternity. I then used a mini paint roller with a rubber glove stretched over it to wedge the blank in place while the sealant cured.
