Working on a model for a future article, I scratchbuilt a door from white Plasticard. It's a simple job – just cut a rectangle out and scribe the surface with an Olfa plasticard cutter.

Next, the door was painted a sunny green to match the windows and left overnight.

In the morning, weathering work commenced with a wash of enamel track colour Humbrol. I'd hoped the paint would sit in the gaps between the planks emphasising them as well as toning down the green.

I'd obviously not left the base colour to harden long enough as it was washed away in places. This could have been a bit of a disaster but I think I quite like the result. The paint looks as though it has weathered, wearing away in patches through the efforts of the sun and rain.
