What a sticky wicket!
I use a spray box. A big box that I put a newspaper or magazine at the bottom (so I can keep turning over unsprayed pages) and a piece of fabric to cover the top. I spray my item in the bottom of the box. Grab my item out, then quickly cover the box with the fabric to keep the smell to a minimum (it's also in my basement so I don't stink up the whole house.)
When the magazine gets to gluey, I throw in another and go to town.
Yup. That's all done........... And still fine spray all over the place
