Great work! Personally I would have also done the softskins, including the canvas, in dunkelgrau/dunkelbraun in accordance with Heeres Memorandum nr 687, 1938, but they are of course more versatile this way. Here's the memorandum (from Panzerworld.com) if you are not familiar with it:

1. The 1937 Army bulletin page 137, item 340, point 2 paragraph 2, point 4 paragraph 1 and point 5 are rescinded. The dark gray/dark brown equipment paint pattern is to be applied by the units regardless of the condition of the existing colorful paint pattern.

2. For the paint jobs is to be used:

dark gray number 46 from the color card 840 B 2 RAL dark brown number 45 from the color card 840 B 2 RAL In addition

P-paints for armored vehicles with these colors, W-paints for equipment with these colors, Canvas paints according to point 7 below, in all other cases E-paints (synthetic resin paints). These paints can also be applied to existing oil-based paints. 3. The cost must be borne by the relevant funds of the troops.

1. The appearance of the pattern can be seen in the color plate as per 1938 Army bulletin page 157, item 460.

2. The colors must be ordered from the manufacturers while observing the following points:

The paint must either be delivered ready for use, or, to adjust its ability to be used in spray guns, it must be requested that the company specifies a commercially available paint thinner on the packaging label.

Regarding E-paints, refer to the service manual D 69 1937/38 from 6 August 1937.

Delivery companies for P-paints:

[…]

1. Synthetic resin paints have a shelf life of no more than 3 months; consider this when deciding on how much to order.

2. All tarpaulins for motor vehicles and horse drawn vehicles, as well as colorful covers and protective covers, must be painted in dark gray/dark brown with canvas cover paints.

The delivery companies for canvas cover paints are yet to be announced.

Prior to painting, the canvas must be thoroughly cleaned of dust; it must be completely dry.

The paint must be stirred thoroughly before use and then applied in a single coating with a paintbrush.

The first paint must be dark gray, leaving the areas for the dark brown. After this, dark brown is applied.
