So quite a while back I make my own paneling liquid, there was a lot of trial and error, and today I decided to make a upgraded batch and share what I do.in my experience this works with any color that you can think of however I mostly use it with a dark gray or black.
First up is materials you will need a empty bottle you choice of thinner relative to the paint you are using and paint. I am using all Vallejo products (personal preference). The paint is Model Color Black Grey 17ml ( 70.862) and the thinner is Vallejo Airbrush Thinner 200ml (71.161). I’ve tried various paints and water before but never got the same results as I did with the thinner and matching paint
First I fill the bottle with the paint enough to cover the bottom of the bottle up to about 0.4 cm. I’m estimating in the image cause the paint wouldn’t move around the bottle like I had hoped.
Next fill the bottle up to 4.5 cm with the thinner and shake well and apply with a fountain pen. Make sure you clean the nib regularly. A simple wipe off with some cloth will do just fine.
Below are some screen captures I got from a video of the liquid at work. I originally hope to upload the video but the file is too large so the screenshots will have to do.
And that’s all there is to it. It is a very simple thing but can make a world of difference. Especially with that pen it helps with the control side of things.
