The Problem with Panel Line Shading

So this is the post where I get to shit all over other people’s builds!
Not really. Or at least, that is not my intent.
My intent is to talk about shading panel lines (mainly pre-shading, but also post-shading), and why – if you’re pursuing a realistic or verisimilitudinous finish, it’s a terrible technique that should be shunned and mocked.
Since there as been some confusion since I first posted this, let me elaborate on a few things.
- I’m not saying all shading is bad. Far from it. Just the kind that tunnel visions on panel lines.
- I’m not even saying that panel line shading is bad. If you’re doing it for stylistic reasons, fine. To each his own. I’m talking about pursuing realism or verismilitude, and then shading the hell out of panel lines.
- I’m also not saying that panel line washes are bad. I use washes on every aircraft that I build. To me the key here is subtlety.
- Verisimilitude – “lifelikeness”, the appearance of being real
Because Reasons
First, let me say that pre-shading actually does some good. It gets modelers – including yours truly – thinking about paint in varying layers of opacity. For that reason alone, it’s often one of those game-changers that elevates people’s build quality, and I think that may be why so many stick with it so doggedly.
I mean, I get it. It’s contrast. And unrealistic, hyperbolic contrast is better than no contrast, right? Just look at the “house style” Hasegawa uses to show off their new kits. It’s utterly lacking in contrast or tonal variation. It’s…awful.

But for all the good panel line shading does, it’s bullshit. Here’s why.
It’s a ton of work. For any kit worth its salt, shading all those panel lines is an exercise in concentration and swearing.


It’s unforgiving. Get a bit too happy with the airbrush and all that work is gone. Play it too cautious and you may have difficulties covering the gray primer or managing the contrast.

Third, it’s just not representative. Yes, the panel lines on some aircraft certainly do get filthy. But look closely. It’s never just the panel lines. And it’s very rarely all of the panel lines. The paint itself gets battered and dirty. Panel line pre-shading (and post-shading) totally misses this, and creates something that looks exaggerated and fake – like one of those overdone HDR images.
Note: I feel I should restate it here: if you’re going after a stylized representation, then by all means go to town. Just don’t make claims to verisimilitude. A Facebook commenter mentioned Monet, and I think that’s a fitting example! Monet was a great painter! But if he made claims impressionism was “realistic”, there would be a lot of laughing.
Look at this Spanish EF-18, for example.

There are lots of visible panel lines…but they are not uniform. And the surfaces of the aircraft itself are filthy, especially around the wingroots.
Or consider this A-6 Intruder from Desert Storm. Plenty of visible panel lines, but they’re all fairly subtle, and there’s a lot else happening on the surface.

What I’m Talking About
Now, I hate to speak ill of others’ work. And that is in no way my intent. But…I have to show examples of what I’m talking about. I’m not commenting at all on the quality of the build or even the rest of the paintwork, which in many of these examples is quite high indeed. I am only showing them to illustrate this technique/style of shading panel lines. If you’re getting upset reading this and want to get all defensive and butthurt about it, that’s okay. One of the examples I’m going to show won at the IPMS Nationals this year, so clearly there is some subjectivity at work. (more…)




When I came back to modeling in 2010, I initially had a lot of questions about glue. After all, my last experience had been building models as a kid, and the glue situation was pretty much as follows:
