Making Your Window
Molding Look New!!

Rodney Bell


Forward by Wayne:
     Here's a small tech article detailing how to get your windshield molding to look much better.  Although originally written for the 914, the techniques and principles can be applied across all the cars.  Rodney enjoys working on his Porsche with his sons during the week.

Is your aluminum window molding scratched or dull? Does it a take away from the overall sharp appearance of your car? Well, before digging into your savings to buy new molding, take a look at what I did!

The windshield molding on my 1974 914 Porsche looked old and scratched, and didn’t contribute to the new paint job on the car.  We didn’t have an extra $200 to purchase new molding, but now mine looks brand new and shining, all for less than $20.


1. wet and dry sand paper (1 —2 sheets of the following grits): 250, 500, 1000, 1500, 2000. Any good Auto Paint Store will have this sand paper in stock.
2. Bucket of water.
3. Shaklee Basic H: add 1 Tablespoon to a bucket of water
4. Mother’s Aluminum Polish
5. Flat surface to work on
6. Lots of patience and elbow grease


1. Remove molding from around the windshield. There will be 6 pieces. I found it easiest by removing the small corner end clips first.  Be careful not to scratch your paint while removing the molding.

2. Clean off any paint or silicon with paint remover/thinner or scrape and sand off by hand.

CAUTION: Be careful when cleaning and removing aluminum molding. It is soft and will bend very easily.


3. Test sand on the BACK of a piece to get the hang of how to do it. It is best to learn this process by using the back of a small area of the molding. No one else will see it and you can evaluate the end results that you want. The next steps teach you how to sand.  NOTE: You will complete the following process, one piece at a time.


4. Cut a 2" x 4" piece of sand paper, beginning with 240. Dip the sand paper into the bucket of water and thoroughly sand the complete surface of one piece of molding. (Remember, you have already practiced on the back and you know what you are doing.)

NOTE: It is important that you always sand in the SAME direction at all times. If you don ‘t, you will probably end up with more scratches  than you started with.

5. While you are sanding, continue to dip the sandpaper into the bucket of water. This helps clean any build up from the paper. The Basic H water also acts as a lubricant which makes it a lot easier to sand.

6. Repeat steps 4 and 5 with each grit of sandpaper.

NOTE: Remember that with each grit of paper, the brightness and color of the molding will change. The main thing to look for is a consistency and brightness all along the piece. If there are any spots that do not match, resand that spot ONLY with sandpaper, one grit lower than you just used. You must follow the process to the end on that one spot. It is easier to see a bad area if you first rinse with clean water and dry with a soft towel.

7. After you have followed this process with all 5 grits, then clean and dry the piece.

8. Apply Mother’s Aluminum Polish, according to the directions on the can.

9. Repeat steps 4-8 on all the pieces, including the small corner clips.

10. Clean and inspect the 19 reattachments clips. If any are broken or missing, you can order new ones from Pelican Parts. Check out their NEW 914 catalogue at this site.

NOTE: This polishing process can be used on ANY aluminum piece.

So now that my windshield trim looks shiny and new, I’m all set to polish the rear roll bar molding as well!!

The Shaklee Basic H product can be purchased through Rodney's Shaklee business.  For more details, please contact him directly at

You asked, "What is Basic H?" It is a 100% biodegradeable household cleaner with 100’s of uses for the home, auto, garden and more. Because it is ph balanced, it does not dry out the skin and it acts as a great lubricant when wet sanding aluminum or paint, etc. When mixed with water in the correct ratio, it can be used to clean the interior, exterior and the engine without hurting YOU, the car, or the environment. It has been around for over 35 years. You can get more information by looking up We also have a personal web page at that site (in the Shaklee Yellow Pages). I love my Shaklee MLM business and we run it from our home. That gives me more time and freedom to work on my 914.

Dave Menken adds the following comments:

I think it’s great that you guys are providing this service. It’s much needed and will certainly help everyone involved. However, I just read the tech article on repairing scratched window moldings and have a few comments:
  • The problem with this technique is that it removes the anodizing which will lead to a rapid deterioration of the molding, not to mention that polished, unanodized aluminum doesn’t look the same as the original piece. You might do your readers a service by telling them instead where to reanodize these parts.
  • Also, this temporary fix only works, if at all, on aluminum moldings.

Early 911’s and 356’s were chrome plated brass.

I hope you understand the spirit of these suggestions is to save you guys from the ire that would be generated by the poor folks who spent many hours ruining their moldings. Thanks for being out there.


Wayne adds:  I'm not sure if the 914 window moldings are anodized.  I didn't think so.  Anyone out there know for sure?
