Different Color Primers affecting shade?

[deltableh]

Does anybody know if using two different colors of primer (lets say, Testor's White Primer and Cobra Color's Black Magic) would affect the shade of bodycoat I'm putting on, which would be a Tamiya Bare Metal? I've got the DeLorean from the second Back To The Future, and certain parts are a darker silver than the main body, so two different shades is actually the intended result.

I would say that this is usually true. The difference in color depends on the color you paint over it. Red and white would show the biggest difference, but every light color will show a different shade.

I never used Tamiya metallics. It really depend on how opaque the paint is.

I would give it a go over some test paint first to see how it would affect it. It is generally the case, but it depends on the paint, how much is applied and all that jazz. You may have to mix a darker shade of the paint you are spraying to get the desired effect.

Normally I would mix darker, but it's Tamiya in a can, AS-12

hmm...then give it a test and see what happens. If you've got an airbrush, you could always spray it, then mask it off and hit it with a very thin mixture of tamiya smoke

Paint a DeLorean? Well, I guess you could do that, but why?

Got yourself a botle of this stuff-




-and a roll of aluminum foil, and cover it. If you want it to look like bare metal, cover it with bare metal. Paint it metallic, and it's going to look like it was painted metallic.

Honestly I'd like to see the results; the wheel flares are probably going to cause BMF to get some wrinkles unless one is very skilled/very lucky. I've thought about using BMF, but before making the plunge I'd test it vs. the Alclad/metalizer route. A skilled artist can likely make either method look real.

As for the intial question, simply make a test piece that's 1/2 white, 1/2 black (primers) and see what the spray looks like. Some of those metal finish sprays are pretty opaque. TS sprays airbrush very nicely if you need to alter the shade.

It depends a lot on the paint. For example, Dupont has 7 shades of primer (from white to black including 5 shades of gray) and each color has to be applied over an specific primer shade to get the exact match with the factory color.

It also depends in how we paint, we usually stop airbrushing when we think that it's completely covered, but that doesn't mean the coat of paint os opaque.

Reference pics?

You're not talking about the nose and tail pieces are you? Because those are actually gray plastic, not stainless steel.

If you found that actual stainless panels are different shades, consider a few things:

a. The stainless steel panels used on De Loreans have a "grain" to them, and will often appear to be different shades from different viewing angles.

b. BTTF was a movie, and they used a bunch of production De Loreans, plus several SFX models. You may have to consider if it's actually an intended trait of the fictional car, or just a continuity error that sneaked into the movie.

In my experience, the metallic paints I've used have excellent opaque coverage, and the underlying color has had very little effect on the finish. If I were you, I'd worry more about how to achieve that "grainy" look I mentioned above...

Oh come on- do yourself an image search.



There are plenty of pics of Deloreans out there.

I know what a DeLorean looks like. I'm part of a driver's club. I love the thing. I'm just wondering how to get shades different.

But the only things called out by the instructions are the nose and tail, which are really gray plastic on the real car.

They shouldn't be a different shade from the body; they're a different color.

Or did I miss the point again?
