Surface scratch on clear plastic of horn push

[Robbiee]

Hi
I'm new to the forum
I'm restoring a 1962 3.8 coupe
My central horn push badge has superficial surface scratches (not deep fissures) which look like they could be polished out.
Is this a do it yourself or professional job?
Anyone know of anywhere that offers a clear plastic polishing service?
Thanks
Robbie

Robbie,

Minor scratches are usually pretty trivial to remove by hand with NevrDull. If they are deep, you might need to resort to 1200 or 1500 W&D - this will leave a slight dish where you remove the material, so don't just polish where the scratch is, but rather feather the removed material out to spread the transition. I have put scratched badges in the lathe and smoothed the surface with W&D so that the curve stays even, but this is more bother than a new part costs.

Also, these badges usually craze with time - multiple tiny cracks appear at 90 degrees to the surface, and extend so deep into the clear resin that you cannot get them out without removing too much material. If yourse is lightly crazed then just polish it and live with it. If the crazing is extensive you may find that the polish ends up in the cracks and highlights them.

And don't even think about a repro one as they are horrible! Use plastic polish or Brasso.

Hi
Thanks for the replies
Don't worry I'm not going for the repro one especially as mines in really good nick...no deep fissures.
Nevrdull sound like the thing as there are just minor surface scratches.
I'll let you know how I get on

"Before and after" pictures would be great, in order to share the method & experience on the Forum.
