Great concept, looking forward to seeing this come together! For flamecap on my sg-1f I dyed the cap with black colourtone before any sanding. Cap was super thin. His revealed aglue spot that I hit with a wire brush. Then sanded back very carefully with 400 grit clog free paper to reveal fłame. I was worried about going through cap but no issues and didnt take much sanding. I did frequently clear sanding dust away with a fine paint brush to see exactly how it was progressing - else the whole thing is quickly obscured with grey sanding residue and its hard to see whats going on.
