heh scribing sounded easy; untill I tried to further define the panels; which were already recessed on my car model.
the knife wouldnt follow the shallower lines. and didnt really make much difference cause the V needed wasnt lining up; more of an ^ cut where they intersected at the surface rather than below the surface.
thought about using my lexan scribing tool; but that makes a pretty big line if it goes deep; so do I just go shallow? or is there a smaller scribe tool for this?
Ares,
The link below is for the scriber I use and it is great. I put the tip in the groove and hold it the tool lightly way down at the other end. That way it will tend to follow the groove better and less likely to wander off in a different direction.

For really small curves or circles I will use one of the tools below. I made these from a set of replacement point for a drafting dividers. These actually were one piece and I cut it in half, drilled out the end of a quarter inch wood dowel and CA’d them in place. A light buff with a Scotch Brite green scouring pad will get in the groove and clean it out a little. A little 600 grit sanding after that and your in business.
I have most of the different tools that are marketed as panel scribers but there are the tools I use most often.
I have had most luck with a scribing tool I picked up at a hobby shop, and have also had limited success with a broken end mill mounted in an old pen.
