to paint panel lines to you just dry brush the model with black
I would say this method only works with raised panel lines. To highlight depressed panel lines I use sienna watercolour paint to achieve a washed out effect across the panels. The watercolour has the added benifit of automatically running through all depressed components thanks to themiracle of capillary action. Science wins!
dunno if this is really what your after but a great effect i like to use to give the appearance of pannelling is to us a solderign iron with a hollw point to mae tiny burn marks. these marks loo just like rivets, add a bit of charcoal if you want and smudge towards the rear of your model. really cool trick!!
WAIT? has he painted it yet?
Here's one method:
After you finish painting the camouflage, but before any of the (water applied) decals, use a water soluble acrylic paint and in a small pallette or dish mix a dark colour that you want the pannel lines to look like.
(Bear in mind it has to be a watery consistency for if it is too thick, it will not flow thru the recesses)
Next step has to be done quickly and possibly in sections/stages.
Load a good, thin brush with your mix and quickly, run it across the recessed panels. Then take a damp (moist, not saturated!) paper towel or clean cotton rag and wipe away the excess and spillage.
If done right and along the path of the wind, some of the excess could look like spilt fluids/oils.
If your all thumbs, you can practice first using any watercolors used for painting (as this when dried is not permanent and can be cleaned up with a wet towel) If you leave the watercolor as the finish, it may fade with time and sunlight and will dissipate when you apply the decals.
The same method can be used for a deepening effect of the recesses in corners and right angles.
Hope this helps!
Why is it so glossy? :? :?:
