Interesting info about the wooden match. Paper matches for applying paint, I have heard of for years, but never the wooden ones until now.
A product that I find very helpful is the "Microbrush". It's kind of like a very small Q-tip on a bendable plastic handle. It is intended for getting paint, adhesives and solvent into areas that are not always easily accessible. Works good for me. They have several types and sizes, and are available at some, but not all, paint supply stores.
