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. -- ----Because I can---- http://www.ernest.isa-geek.org/ ------------------------ |
