Using 3mm MDF board to make Turret Boards for guitar amps.

Don’t forget that valve amps and radios had been around for several decades before Leo started building his musical instrument amps, so construction techniques were already well established. What wasn’t around were the huge range of plastics we have today. So he’d have used the standard materials available at the time, but better ones now exist.

Fibreboard will absorb liquids and so can become contaminated. Glass fibre won’t absorb liquids to any noticeable degree, so any contamination should stay on the surface and can be cleaned off.

Yep, that's true, before eyelet boards and turret boards were used, the various passive components were soldered point-to-point style between the valves, while that method did work, it tended to look a bit messy.
