Got a rattle can of Helmsan polyurethane to coat a plywood fixture
that's going to get wet. Well, all went well for the first two coats,
but halfway through the third, with about a quarter of the can used, the
damned thing stuck open and wouldn't stop spraying. I tried pulling up
on the nozzle and that just made it start shooting out the top after the
nozzle came off. So I sprayed the basement steps until it was empty (I
would really rather have swept them first but putting something on them
has been on the to-do list for a while so it wasn't a total waste).

Never had that happen before, usually they clog before they're empty.

Annoyign thing about this one is that I can't even take it back for
credit--who's gonna believe that I'm not just trying to mooch a freebie
after I used it up?
