Jayson: You've got it. I've used the stuff you brush on with a small brush. I guess the spray would be fine. I need some so i'll be searching locally first. Thanks guys

I prefer black marker, cheap, easy, and can be reapplied as fast as need be without using a brush.

Marking Dye. We use blue on fan/turbine blades that are blended on jet engines. I think Dykem is the brand.

I have a couple of blue magic markers I have been using for lapping valves and porting intakes, works well and is easy to find at thrift or art stores.
