I just like the smell of MEK (and Acetone for that matter). But, as I
was pointing out a PROPER respirator is essential ...the charcoal
filter, organic vapor type. With the correct filter there is no odor of
solvent what so ever. The presents of MEK in the dope and the fabric
glue is one of the reasons to use a good two part urethane or industrial
grade epoxy to paint the fuselage tubes (or the correct powder
coating).The fuselage coating does not have to resist immersion in MEK
but does have to handle it until the solvent evaporates out during
application.


Just a little info.

I got a blurb about using appliance epoxy, so I ran a test. Painted a
piece of scrap tube with the appliance epoxy that you can buy at the
local hardware. Threw it in a coffe can of MEK. It was completely
submerged. Sat it on a shelf and literally forgot about it for several
weeks. Came back to use a little MEK, and there was my little piece of
tube. I had cleaned the black coating from the factory off of half of
it, sanded to bare metal. The black coated half had not paint, the bare
metal part still shined bright white.

I just have to believe that the stuff they sell to normal plebes can't
be as toxic as the 2-part, industrial grade, wear-your-hazmat-suit
stuff. I'll probably find out I'm completely wrong in a few years.
