Did you spray it black with a can m8?
and what are the guidlines if you dont mind linking
Basically you need approx 1 3rd of the vehicle black. The idea is to disrupt the outline of the vehicle to make it harder to see at distance. So the corners should always be done. Ive painted a fair few tucks and land rovers in my time in the army and its fairly easy to spot one thats been done by a civvie who hasn't done their home work. And yes my black is done with 4 cans of satin black. My green is satin too.
Below is a good website if you want to read more. Ive copied and pasted a paragraph that may explain it better -
Ex Military paint guide
There are no exact requirements for the type of disruptive pattern used, but must follow some general principles:
Units must not reproduce patterns exactly from vehicle to vehicle as this could identify their unit.
For maximum effectiveness at long ranges large bold patches should be used, in general only five to six areas are needed on a smaller vehicle. Little is to be gained from painting patterns on objects as small as a two-wheeled trailer.
Intricate patterns are not necessary, and bold rounded patterns without straight lines or angles should be applied.
Patterns should extend over corners and edges and disrupt the appearance of recognition features such as turrets and lockers. Areas of the vehicle that contain a shadow can give a characteristic appearance to the vehicle; these areas should be distorted by extending them with black paint.
Approximately two-thirds of each vehicle should be green and one third black, this gives the optimum protection at extreme ranges.
The black paint is only available as a brushing paint applied over the green. If the green/black boundaries are merged by the use of sprayed green paint there is a slight benefit at very short ranges, but this is not encouraged as brushing of black paint is considered to be quite adequate.
