I personally don't smell it when I am using it, however you may because of your past exposure. I find that it is a nice flowing medium CA that bonds relatively quickly and quite strong. Firsttime I used it, I repaired my Thor Sturgeon stabilizer poolside, and had it back in the water about 40 minutes later. The repair is still holding a year later.
When surfaced, the bridge access hatch can be optionally open or shut, however, when submerged it is required to be shut. (Really a no s***t precaution from a procedure in use in the sub fleet today.)
