Hey everyone
I have just purchased this beautiful Kriesler 11-50 Fire engine red radio.

http://s971.photobucket.com/user/stephens60/media/Untitled_zps688aac04.png.html?sort=3&o=3.

Sadly it has had some damage to the top and as a result has had some fairly heavy scratches put into it

Does anyone have a technique to remove these I was afraid as this is my first modern plastic radio that a cutting compound like kitten may be to harsh on the plastic or even a very light sand. Has anyone managed to safely remove scratches similar to these?

Thanks in advance
Stephen

I've removed light (not deep) scratches in plastic cabinets using this method:

1. Sand the entire area with very fine wet and dry soaked in water with two drops of dish washing liquid for lubricant. Do this until scratches are no longer visible. You'll end up with a dull surface.

2. Rinse surface well with clean water and dry thoroughly.

3. Polish well with Autosol liquid metal polish. Lots of elbow grease required, but very careful not to overstress the plastic and crack it! Put something behind it to relieve the stress.

Strongly suggest that you first practise this on the inside of the case.

For GTC's stage 3, you could also use Megular's PlastX, available from auto parts places. It's designed to polish and fill scratches in auto headlamps etc and I have used it successfully on iPod screens and plastic bodies.

Those three deep grooves on the top look like they might be cigarette burns from a butt left smouldering on top of the unit - signs of melting at the edges? You would need to cut pretty deeply to eliminate those, with risk of ending up with a visible depression top centre of the case. For that reason, I would be inclined to try first with a clear plastic filler, and go to deep abrasion only if not satisfied with that.

Another product is the kits that used to be sold for filling scratches on CDs, but you would need to test that the solvents were compatible with your Kriesler case or you could end up worse than you started.
