stainless steel (guess?). If that's the case, will you or did you PAINT The monofilament line? If so, with what type of paint?
I have used stretched sprue in the last two builds, and have had good success, but they have been 1/72 and 1/48 aircraft. The current build, a 1/32 Gee Bee could benefit from the larger diameter, and more uniform thickness of mono-filament line.
