On a rare visit to a "real" hobby shop in Columbus,Ohio recently I was browsing in the Tamiya tool section and spotted their part number 74017-400. That is a set of two metal paint stirrers. They are 6" long with one flat paddle style surface on one one and very narrow spoon shaped other end.I have a project on my workbench right now with some challenging areas where putty application is awkward at best. I can't get the putty in place using any of my normal methods due to space restrictions so this looked like a viable solution. These are not cheap at $ 8.00 a pair but are working perfectly. Check them out as they might also work for you.
