Hello All,
I was jsut wondering what the difference is between white/grey/black primers? Would your primer color change based on the base coat of a model? Do you use light primers with light color or dark colors with light primers...ect etc...?

Thanks in advance,
Sean

Sean,
the difference between the various primers it's quite hard to explain. For instance the Tamiya white primes has a finer grain than the gray one. I've never seen a black primer, but I use a white acrylic one that's inexpensive, water "thinnable" and "airbrushable" that I buy at local art srafts stores that can be "coloured" just adding some other acryl colour.
I usually prefer to use it plaun (white) or with the addition of a couple of drops of flat black to turn it in a grayish one, because I feel easier to identify the problems on the model. If you use a very dark one it can be used as preshadig, but for me is more difficult to paint the base coat keeping the preshading on a completely black primed model than preshading on a "light" primer independently from what base colour I'm going to use .
Ciao

Only use black if you are going to be using a very dark color over it, or you are looking for a special effect. I usually use a 40% gray on my military models and Tamiya's White primer on my cars.

I agree with TwistedFate, I use grey primer on armour and white primer on aircraft.

All right everybody, thanks for the input-- that clears up alot of questions I had.
