KX3: Scuff marks on display cover

[Nick Kennedy]

I’ve got some scuff / scratch marks on my KX3 display’s cover. (Yes, shame on me!)

Is there any kind of buffing or cleaning agent that can fix this? Or would it be better to order a replacement from Elecraft?

73-

It depends on how deep the scratches are.

The easiest is Novus polish — a sequence of three products, available as a kit from Antique Electronic Supply, Amazon, etc.  This is best for minor surface scratches.  Micro-mesh is also really good, and available from Aircraft Spruce and other places no doubt.  http://www.aircraftspruce.com/catalog/cspages/micromeshstd.php

I’ve used both products many times doing dial cover restorations, with the Micro-mesh better for deeper scratches.  Of course, ordering a new window is the easiest and most foolproof. :-)

Nick,

The easiest is to use a bit of oil on a cloth and rub the area with some
pressure.
That will take care of scuff marks, but it will not eliminate scratches
that have gouged into the plastic.

If the plastic surface has been gouged, I think the best thing is to
order a new bezel.

I found that putting the clear shipping tape on the display before going into the rough will save the display.

A slightly more aggressive approach is to pick up the headlight lens cleaner sold at most automobile stores - the stuff that takes the "yellow" haze off of plastic headlight covers. It's also sold for use on aircraft windshields to polish out the scratches that inevitably come from charging through the air at 150 mph or so (but that costs 10X as much because it is sold for use on "airplanes").

All you do is wipe it on, rubbing aggressively with a cloth and then, as it turns white, wipe it off.

I've read of people using toothpaste with the same result. (And then you'd have a fluoride protected lens that won't get tooth decay.)

This may help in weighing your options,

Toothpaste.

Colgate.

I was taught this by a jet airplane mechanic when I was 15. That's what they used on the windscreen.
