Howdy!
I read somewhere, about people using black paint as a primer for armour models.
So I´d like to give it a try, but I´d like to know, what I´ll get using it (why to use?), and how to proceed to use it.
Any comments are welcomed!
Cheers!

Paulo,
I now use Polly S grimy black. It is a railroad color,kind of oily looking. But other guys I know use just plain flat black. Any brand, cheapest you can find. That way, if you miss any corners when you airbrush your final coat of paint, it isn't that noticeable.(sp).
Either spray straight from the can or spray some into a larger container and pur into your airbrush cup.

After priming with black paint, how well does primary color cover? And do you sand first?

I have had no problem with color coat coverage over black primer In fact, if you go light on the color coat, the model looks grimy. (how do you spell this word?)
That is why I like building armor, no sanding required except for parts clean-up

I'll think I give it a try, I am just about ready to prime a Tamiya jeep, and I know I have a can of Testor's flat black, I'll give it a shot.

Many thanks for all answers.

Pipesmoker, do you use it as a preshading(that´s right?), if so do you chose to left some areas with just a cloud (???don´t know the word!) of light sprayed painting? For example, in crevices, etc.
Cheers!

Paulo, when using black as a primer, it's primary purpose is for pre-shading. In order to achieve this, you need to AB your top coat lightly at first with sort of a plan of attack.
I start by spraying in the center of the panels first while slowly working the paint towards the edges of the panel lines. You don't want to completely cover the edges or the panel lines of the black. Ideally you want just a little of it to show through the top coat along the edges or panel lines of the model.
This way you create an artificial third dimension to the model. It really adds some depth to the surface. When done just weather as usual.

Right....exactly what Ken said.
