epoxy coating airbox? and material question.
designed this airbox for my dual DCOE carbs, with a filter which goes in the middle.
I'm debating whether to print it with ASA (easier and faster to print) or with pa12-cf.
printing with ASA will require me to coat the inside with something otherwise fuel fumes from the carbs will distort the ASA, if I go about using epoxy to coat the inside and outside,
how would I go about doing so and what kind of epoxy?
other option is to print with the PA12-CF. which won't be affected by the fuel fumes, but then my concern will be about the small carbon fiber strands in the filament that could potentially break off and go into the engine. (if that's even an issue?).
any suggestion about what material and how to epoxy/coat the inside will be greatly appreciated. thank you
