Covering the rather visible PCB inside the railbus proved tricky. I don't want to take the components out as they provide suppression for electrical noise as well as DCC stuff that might be useful in the future. There's nowhere to relocate it either in such a small model.
The solution came from an unexpected source - looking at a model boat at Bristol and talking the the builder, he showed me how the cover on a liferaft had been made from clingfilm. It stretches perfectly to look like tarpaulin and will accept paint.
For his application, I wondered if it might be a bit fragile but to cover the PCB, perfect. Thin and non-conducting, it adds nothing to the bulk of the unit and painted black isn't too obvious. Took 2 coats though as the first dried gloss, presumably something to do with the material.
I suppose I could pretend this is some sort of covered "thing" being carried but why would it be sheeted when inside the body? A bit like those people who insist on wearing a woolly hat indoors under a perfectly good ceiling.
