cheers eastern, for the alcohol, you think tamiya thinners would be ok? hope fully i can find white weathering powders, last time i was in my local hobby shop they had no powders at all. mind you the whitewash i have in mind , if i can follow the picture, i'm going have a go at putting it on with a cotton bud. the real one looks like it was put on with a roller

i'll have a practise first though.
