TR2/3/3A Removing scratches and scrapes fro the wind wings that screw to the windshield?

[karls59tr]

Has anyone successfully renewed the plastic wind wings and what did you use?

It's a lot of work, but aircraft windshield polish will clean up minor scratches. Use aircraft windshield polish, not just cleaner. PJ

Wouldn't it be easier to just replace the plastic?

I used auto glass polish on the perspex in my 26 Chev and they came back like new try a small section first to make sure it doesn't make it look bad.

If you replace the plastic you will probable not be able to match the curve in the lower section of the wind wing.

Sorry, I just assumed it was flat, like the Earth.

There is a product made by Novus for this specific purpose. Their website link: > Restore Faded Plastic, Plastic Restorer | NOVUS Plastic Polish <

From my experience (I owned a plastics fabrication company). Restoring plastics is not an easy job. We kept Novus around, but it only worked on very superficial scratches.

One other thing... acrylic plexiglas can craze. It is that crazing which makes it virtually impossible to restore. Get a magnifying glass or thick glasses and look carefully at the surface. If you see very very fine cracks under the surface of the plastic then the restoring the wing is a lost cause.

The most common reason crazing occurs on plexiglas acrylic is because it was cleaned with windex or some other ammonia-containing liquid.

It is possible to make a new piece. If you want to know how to do that I will tell you. Just let me know. It may be a project you would enjoy doing. In truth, the time and effort it will take you may not compare with just buying a new wing.

Is there any truth to the old tale, of using toothpaste, or auto rubbing compound, to polish clear plastic, like headlamp covers?

 

[Graham H]

My boys have used auto-rubbing compound on headlamp covers with great success, they come up like new

car polishing compound works well on plastics, I use £arecla G3, £innishing o£ with G10.
Best done with small a polishing mop,
