Thanks for your nice comment and my access to vbench
For the disc cammo I used low stick band for fine surfaces, a perforator and a punch and die set
I put the tape on both sides of a thin plastic plate and cut different sizes of rounds out of them
With a sharp knife you can take the rounds of the plastic and put them on your kit
spray the yellow paint over the whole thing and remove carefully the roundels with a knife again.
You can correct the painted round with the opening in the tape of the same size and over spray it with the cammo color
This method is quite time consuming but it gives a good result/
