Impressive stuff!
When you are painting say the area around the outhole in the white, do you stick down the contact and THEN cut out the bits you want white?
Do you use a guide to cut or just have a really steady hand?
Yepp, i just stick the contact down first, then cut out the areas to be painted. I dont use any guides to cut, its all done free hand, i just take my time and cut carefully (except when i need a dead straight line, then i'll use a steel ruler as a guide).
