This 1/144 RG Zaku Custom was posted on our CustoMecha Official Group by Ms. Ellie aka EL.S. I lurk on the comments to find some info on how she did it (sorry Ms. Ellie haha!) and this is what I found out. According to the modeler:
“I didn’t use primer for this kit. And yes neither topcoat, but I choose to mix the clear coat with the color that been used in each part. With around 1:6 composition (colour:thinner) as thin sprayed it over the parts.”
Thanks Ellie!
