I think that's what I did, and just "blipped" the gun at the various angles to avoid too much buildup. Either that or I used my Badger 250 airbrush. Can't remember. I kept the airbrush handy for tight areas like that.
Of course after admiring the perfection of the job, a few weeks later the lower cowl fell over and hit the hangar door putting a nice gouge in the scoop.
