I've had this Airsoft Sniper rifle for about a year now, and got sick of the blue stock.
so I thought I would revamp the gun with a better more authentic look.
Step 1: How Things Used to Be
They look pretty cheep and tacky.
Step 2: The Strip
Unscrew the strap loops and any other removable parts.
Key the surface with fine sand paper, then clean the stock with and alcohol rub.
Step 3: The Undercoat
Allow this to dry, apply another coat if required.
( I did try a matt black coat, but the gun looked as plain as porridge).
Step 4: The Top Coat
Apply this coat with a brush, draw the brush from top to bottom in one smooth stroke,
this should give it a grain effect.
Touch up as required.
Step 5: Reassembly
It can take a day of so to dry properly.
Step 6: Other Effects
The camouflage was applied with a small sponge and brush.
I used acrylic paint for the jungle effect..
