Hiya Tex. =)
I'm still working on that a little, but I don't want to eliminate the lines entirely. We've gotten used to seeing the lines there, and trying to emulate a line that would take literally .1 pixel with a 1-2 pixel range minimum is very difficult. Also, depending on which seam, and what angle the light is can make a huge difference as to whether or not you can see the seams. Here's a couple of examples to see what I mean.
Even with this poor picture quality (on a 2 seated P-38) you can easily see the panel lines on the engine fuselage.

Here's one of a P-38 nose,

And one of the underwing / inside fuselage

I definitely want to see about getting some of the "deformation" around the seams if I can. I thought I did have that on at one time, but at some point I must have removed it for some reason... Hopefully I'll have a few more pics in a couple of days.
Thanks for the advice, every little bit helps =)
