Strike's main body done with rust weathering.. (the lazy way)1- Very straight forward, apply gray real touch wash,you'll get something like this. a subtle shade of oil stain.2- Apply brown real touch marker for a hint of rust. apply as random as you can.3- then, a lighter brown highlight.Same goes to other parts..Eventually, you can get something like this.. well, its not perfect. But it looks like strike is being used and rusted a little.General update for RG Strike, now.. its time for decal
