To be honest, after cleaning the case today it's not so bad. They keyboard is a disgrace though. I will clean the keys up and try it on those. People recommend a dishwasher for keys of what I've seen. Then I'll cook up the retrobright and fling em in a bowl of it and mix them about. Does it definafely need sunlight to take as I live in the uk and it only ever rains. My best bet would be a garage or the garden shed in a bowl covered in clingfilm to keep them from the elements. I don't mind leaving them over night or applying a second coat.
