Dual Diffusion Method

Tamiya's 1/48 scale MiG-15bis Clear Edition is available online from Squadron.com




This is Tamiya's 1/48 scale MiG-15bis.



The model was built with an Aires cockpit set and Hi-Decal markings. The model was painted with Gunze and Tamiya acrylics and weathered exclusively with my Iwata Custom Micron B using my dual diffusion post-shade/post-fade method. Chips were made with a silver pencil.



"Dual Diffusion" Method


There seems to be quite a bit of confusion on the internet about my "dual diffusion" method, especially from some guies who are not getting the desired results from using the method. It's now time to reveal the true secret of dual diffusion.

Two years ago I approached scientist Groiheimisch MacGinge from the Canadian Army Fluid Dynamics Research Centre because I was looking for a way to paint my models quickly, without having a system that would become a troublemaker.



He suggested that I use a splitter hose and hook up 2 Iwata Microns in a side by side "mistel" configuration. This way I am able to paint both the post-fade and post-shade dual diffusions simultaneously.

This is a real time saver, the only thing you have to watch for is if you reach around to adjust the pre-set handle on one Micron, that you do indeed turn the correct knob.
