I was looking for a good write up on weathering for a blaster and will use your technique. Some questions on sanding though if you do not mind. Am I to understand you sanded your weapon after assembly? How did you get into the tight and tiny crevices to sand? Also what was your processing for sanding, ie grit type, and did you use paper or a sanding tool? Any advice and tips would be greatly appreciated. Thanks much. Jake
