Reducing Windnoise / Raingutter Fillers

I build a vacuum forming machine out of some wood I had laying around in the garage, and a set of electric BBQ’s. Laughing
The households vacuum cleaner provided the vacuum, and after some failed attempts, I got succes!:

(for people who get bored quick, skip to 2:00 minutes for the action)

 

The result:

I had to cut them out, and give them the right size. After that I sanded them a bit, and used a ratle can to paint them matte black (the plastic had scratches). Because the plastic is fairly thin the surface is not super-smooth. But the matte black covers that quite nice.

See the next page where I’ve got them installed and tested.

    • Hi Jürgen,

      I have sold a few sets, but not much. They are still a bit “experimental”, I create them out of thin plastic using my homemade vacuum former.
      They require work to get smooth too, it is not a nicely finished ready to use product.
      I don’t have any sets “in stock” currently. I sometimes create them when more people ask about it, and then I create a few sets in a batch.

      Greetings,
      Gerrelt.

      • Hi Gerrelt,
        my request is nearly 1 year ago. I am still interested (as Jeff Kritz :))
        How long is your mail list of interested guys?
        We are just in front of a new Season……
        All the best for 2017
        Jürgen

        • Hi Jürgen,

          I see what I can do… 🙂
          I hope I will produce some this year, preferabele before the season starts of course..

          Best wishes for 2017 to you too!

      • I have been trying for the longest to purchase a rear roof spoiler and a pair of reflectors from you without success. I’m reaching out again.

    • Hi Jeff,

      I can add your e-mail to a list, then I will inform you when I make new ones (but that take quite some time..).
      A set will cost around 30 euros.

      Greetings,
      Gerrelt.

    • Hi Khalid,

      OK, I will add you to the list.
      Yes, they will allow water to pass underneath. They are hollow, and there is a hole at the top and the bottom.

      Greetings,
      Gerrelt.

  1. I would also be interested in a set of these. I already have one of your rear window spoilers. Thanks.

    • Hi Rick,

      I will add you to the list (and make a mental note to start making a batch again…).

      Greetings,
      Gerrelt.

  2. Hej Gerrelt,
    here is one more to put on your list for gutter fillers. After traveling Germany north to south and back in my VW 1303 Bubster, I feel that I am in need for some aerodynamic upgrades. Wind noise is quite bad when cruising at 160-180km/h.

    • Hi Olaf,

      I just spent an hour or so going through the excellent build thread of your Boxer Beetle. Wat a brilliant build, very nice!
      Very cool car.

      I will add you to the list, and try to make some time soon to make a batch….

      Greetings,
      Gerrelt.

  3. I’d be interested ina pair of these gutter fillers and a rear window spoiler also. Can you get in touch if you have any for sale currently?
    Thanks
    J

    • Hi James,

      I am currently producing a new batch, but they will probably all be spoken for.
      Shall I put you on the list?

      Greetings,
      Gerrelt.

      • Hi, yes that would be good, but it also depends on the price including the roof spoiler.
        Maybe you could email me?
        Thanks!

  4. Gerrelt, very cool stuff you are doing.
    I am interested in the rain gutters and rear window spoiler for ’74 Super.

  5. Hi Gerrelt
    I’m also interested in a set of rain gutters and a roof spoiler. Do you still sell them?

    Best regards from Germany
