really your supposed to "step" your sheetmetal when doing that.. they sell various tools for it from an air stepper, to an air hammer bit..
but you can often cheat by just kinda bending the last inch or so down slightly... hammer/block of wood when done, etc.. just can't let it fock up your gapping....
I like to seal em up.. than install a pop-in a plastic plug (like Adam recently bought) at each end at the bottom if feasible.... like 3/4 or inch hole.. that way I'm can douche paint up in there..
i'll actually take my gun, put it down to stream and spray it all up in there till it's dripping out the holes.. but, that's me...
