[TrunkCom] Scratch Fixer

[Brandon C Nuttall]

Folks,

First, I haven't actually used any of the various compounds for fixing 
scratches on plastic. But I'll give you my 2 cents worth anyway.

What you need is a "polishing compound" or "jeweler's rouge". There are two 
basic strategies for fixing a scratch. One is to fill the scratch; this is 
the basic principle behind the wax pencil type scratch removers that work on 
furniture. The other strategy is to remove the scratch (analogous to 
sanding). The hardness and grain (or grit) size are the properties you need 
to be careful of. The smaller and harder the grains, the more highly 
polished the finished product.

Polishing compounds come in many formulations. A common polish is Brasso; 
you'll probably find it in your local grocery store. I've used it to put 
mirror finishes on metal parts. However, Brasso is a liquid that may be (at 
least in part) a petroleum solvent. These solvents are often harsh on 
plastics (maybe even dissolving them). Other polishes come in sticks.

You might try visiting your local hobby shop that has the biggest selection 
of plastic models. Many people that customize the models use a variety of 
cutting and polishing techniques when building.

There are buffing and polishing wheels and compounds available for common 
tools like the Dremmel rotary tool. When using rotary tools you will need to 
be careful not to overheat and melt the plastic.

My suggestion would be to make a selection of a jeweler's rouge. Check the 
instructions to verify it works on plastic. Get a small piece of scrap 
plexiglass and scratch it. Try your technique and compounds on the scrap. 
When satisfied, try it on your scratched equipment.

OR, contact the manufacturer and ask them for a replacement part.

Good Luck.
