Painting recessed lettering
Painting recessed lettering is a breeze if the surrounding enamel has been baked on. You'll want to apply the paint to the lettering with a soft brush that has fine hairs, while making a casual effort to stay within the individual letter boundaries. Make sure the paint is just thin enough to flow out after it's applied, thereby erasing the fine striations left by the brush. Now using a rag or a cotton swab that is damp with thinner,(not dripping wet) carefully wipe away the excess lettering paint that strayed beyond the edges of the letters. If the surrounding enamel was baked on, it will be completely unharmed by the thinner. I've used this process many times with very good results. If you have any doubts, try it for yourself on your actual project prior to stripping it for repainting.
