Re: [Chrysler300] plexi glass?? instrument lens and emblem lens cleaner

[Bill Huff <czbill@xxxxxxxxxx>]

I used dish washing soap and hot water to remove the gray goop.  I 
resealed/rebedded with a black silicon RTV ( I think, it has been 
several years).  For plastic lenses, if they are not scratched or 
marred, I like toothpaste.  Yes, toothpaste has a very fine polishing 
grit in it.  It is finer than Brasso and can be kept wet with water 
to keep it working as the grit breaks down into finer particles.  If 
the lenses are scratched, I use fine wet-dry sandpaper to smooth it 
down.  I usually start with either 400 or 600 grit, depending on the 
depth of the scratches to achieve a smooth surface and then work up 
through finer grits to 1200 grit and finally 2000 grit, alternating 
sanding directions with each new grit.  I think you get better 
results with straight sanding rather than circular.  After that the 
toothpaste provides a final gloss finish.  Best to use a small 
sanding block with the sandpaper to avoid finger grooves.  Mask off 
any non-removable trim pieces.

This is a procedure my father (amateur watchmaker/jeweller) used to 
refurbish plastic watch crystals when replacements were not 
available.  Left them looking new.
