What type of engineering considerations (corrosion prevention, electrical conductivity,...(?) ) needs to be made when approving particular painting materials, e.g. paint stripper, filler, primer, topcoat, etc.
1) Story going around of a private owner who used automotive wax for buffing his a/c. Unfortunately, this contained a silicate which played havoc with the aircraft radio systems. Aircraft eventually had to be completely paint stripped and repainted.
2) The current batch of commercial paint strippers are acidic*, where as the paint strippers used in aircraft standard practices are basic*. A problem we found with the commercial paint strippers is that they would remove the Cad plating of the aircraft hardware. Apart from this**, there appears to be no reason not to use the commercial paint strippers.
DO NOT SAY: "Follow the aircraft manufacturers instructions." Often the only painting material approved by the aircraft manufacturer is of paint materials no longer available or exceeding difficult to source.

*Might be the other way around
** Instructions: "Remove all cad-plated hardware prior to paint strippin
