[R-390] Polishing

[Jon & Valerie Oldenburg]

Barry- MFP is a alcid varnish product using mercury compounds for the fungal
resistance. These varnishes are very solvent resistant,  and are evident as
a semi clear yellow tinted over coat on all components of  a treated radio,
most treated radios are stamped  "MFD"  in a diamond shape on the chassis
after treatment.  Alodineing is a chemical process similar to anodizning and
is more likely to be damaged by accident, MFP is very tough to remove.  Jon
