no...spray the clubface. I'd say for sure it's a training aid (so what? if it's a 'practice' round, use it, learn what you can, don't post the score for handicap purposes - or do it at the range). It cleans off pretty easy too.
at the indoor range, the balls are grimy a bit from all the wear. If I start with a clean club face, it only takes a few shot to see my impact zone. I think that's a bit more revealing because it shows the stain after several balls, not just one. Surprising that the mark isn't very big. I'll take pics today if I remember and post. They show up fastest on the wedges - makes sense since it's more of an oblique impact...(i.e., it rubs)
