So having a problem with grey spray on primer as a basecoat (airbrush not an option for my living situation sadly) and need a second opinion. This is mainly in regards to vehicles as I prefer to hand paint my infantry minis.
My army's base color is GW Mechanicus Standard Grey. The only catch is the brush on and spray can colors are not an exact match. Despite using a white primer for the brush on I've found that laying a black primer is the only way to get a close enough comparison as the spray comes out a lighter shade than in the pot.
Have been experimenting with Army Painter Uniform Grey Spray which is a darker tone, but am not 100% certain its a match. Anyone have any ideas or experience with this issue. I have basecoated the Army Painter spray on directly with no underlying primer as per my FLGS's suggestion.

Bike - Mechanicus Standard Grey Spray on Black primer
