Kurt, what local club are you a member of?
I purchased that engraving tool , I think its a new item from Tamiya, and the thinnest blade, and I will be doing a full on product review of it when I get it over here from Japan , next week hopefully. I bought it for this very thing, to deepen panel lines without expending them outwards that a lot of the panel line engravers do, so I am hoping for the price it wont as bad.
