took about 3 coats after a 4050 primer to achieve the desired level of coating i wanted for my project. Worked really good, would highly recommend to all painters
I am very happy with the black primer. I have used the primer as both a primer and as a paint when I was out of black paint. I found after applying a colour over the primer, the primer assists in creating shadows along panel lines for weathering affects. I did notice MMP Bronze Green for British AFV took to the black primer with better effects than the white primer and gave the Bronze Green a darker appearance.
