How to Paint a Camoflauge Pattern With Rust Effect

I have been asked to make an ible of how to paint a camoflauge pattern with a rust effect as in my https://www.instructables.com/id/Camoflauge-B-ATM-03-FATTY-GROUND-CUSTOM-airbrushe/...  Well, here it is!

Step 1: Materials You Will Need

You will need in general for the rust effect:
Aibrush ( I will be using the Sparkman 2.0mm)+ airpump
Tamiya (or any other brand) brown (and I mean many types of brown, preferably 4) acrylic paints (and maybe a green or two)
Something to paint (I will be using a white Lego block)
Water
Salt (I will explain why you need this later)
2 containers
toothpicks + Masking tape (or something you can use to hold onto the pieces)
blocks of wood with holes (or something to hold up your wet painted pieces

Step 2: Prepare for Painting

Attach your pieces to the toothpicks (I rolled tape around the tootchpicks so they would fit in the lego piece's hole)

Step 3: Paint the Base Colour (Brown)

paint a thin, even layer of brown (X-9) with your airbrush. Wait for it to dry.

Step 4: Paint Spots of Green, and Red

Randomly paint spots of Dark Green(XF-61),Hull Red (XF-9) . Make sure it does not stand out alot but also can be seen.

Step 5: Salt

Once the pieces are all dry, fill a container with salt. Take a paintbrush and wet the peices around the edges and dip into the salt. Make sure the salt sticks onto the piece. Dip the paintbrush in water again and lightly touch it to the clumps of salt to make them wet and stick better. Wait until it dries.

Step 6: Choose Your Camoflauge Colours

Choose which type of camoflauge you would like a plane camoflauge, space camoflauge, desert, jungle..... I will only be teaching a desert camoflauge, but for other kinds, just change the colours used.

Step 7: Choose Your Camoflauge Type

Spray your model (or lego block) with your base colour (desert yellow) in a  nice even coat. After that, spray your detail colour(s) in wavy lines, dot, or just random shapes. your model should now look like mine in the picture, except you should have clumps of dried, coloured salt on yours.

Step 8: Spray a Clear Coat

Well, basically do what the title says. Make sure your clear coat is not laquer (i have no idea how to spell that) or it will melt off your previous paints. Make sure your clear coat is not water-soluable. I used a floor shiner, but anything will do. (sorry no pictures)

Step 9: Wash Off the Salt

Wash off all the salts by lightly scrubbing with a towel. Some of your base and detail paint will flake off, but no matter, this will only make your model look more realistic. Dry your model, and enjoy! =)
