I am considering acid etching the deck of my scratch VIId in order to get the required detail.
Research on railway modellers and electronic PCB sites would indicate that there are 2 possibilities:-
a> proprietary iron-on PCB sheets on copper
b> UV expose brass sheet using photoetch chemicals from maplins (UK version of radio Shack)
Both methodologies sound straightforward but I would value practical advice.
a> Thickness of sheet? Brass or Copper? How much depth can I expect to be able to etch? Could I etch straight through?
b> Should I apply the etched sheet to the fibreglass plug to create a pattern in the mould or should I apply the sheet to the finished model.
Sorry to be always asking questions. Maybe when I finish this I will be able to contribute more.
