The drop pod has a lot of flat areas and a great way to lift the model is to apply wear and tear to the hull, which is the choice many painters have done with their drop pods and this is how I did my wear and tear effects.
First step is to apply the base colour of the tears at some selected areas, Around corners are a good choice and where the doors might hit the ground are also good places. I used adeptus battlegrey to paint the first layer of wear and tear.
The second step is to fill in the areas which have been painted with boltgun metal. Make sure not to fill in all of the area and let some of the grey still be visible.
The third step is to highlight and darken the tear effect, I did this by applying chainmail to the raised areas and a very thin line of badab black to the lower and right side of the tear.
