[ RadSafe ] Restoration of plastic display covers on meters

[Ted de Castro]

Yes there are plastic polishes that work quite well - I have one - but 
its mil surplus --- so that won't do you any good.  BUT - like someone 
else said if the headlight lens stuff is for plastic - it SHOULD work.  
ALSO - for those soft plastic windows in convertibles which ALWAYS get 
messed up - the recommended polish is McGuire's - should be available at 
any auto parts store.
