I have yet to decide what epoxy to use on my steel fuselage, so I have
no literature on how to prep the metal.

Part of my decision making is _where_ to do the work. If I have to use
MEK or like solvent, I don't want to do the work in a semi-enclosed
area; if a dry wipe-down or alchol is sufficient, then my work-place
of choice is OK.

Assuming I"ve brought to fuselage back to bare metal and have used
emery cloth so there exists a 'tooth' to the metal, does metal prep
require the use of MEK or acytone prior to primer application? - Mike
