Planet blue metallic is a straight metallic.
No candy.
So put on a ground coat - for instance grey.
Than simply spraypaint the planet blue metallic.
You can also use a spray can - aerosol for this.
Apply decal and clear.
Thanks for clarity on application. I also read your veiws on RS paints but as other paint manufactures wont post to UK will have to use RS.
Also now in contact with Diego
