There are many different ways of weathering and thanks to Dr. Cranky for his videos and pics on weathering... This is how I do mine...
I've had quite a few people asking how I go about weathering my cars...
This is by far the easiest way I do it...
Supplies needed are
Red oxide or ruddy brown primer
Satin or flat color spray paint
Table salt and/or sea salt
Cheap bottle acrylic paint ( burnt umber, burnt sienna, marigold)
Cosmetic sponge
Old toothbrush
As always clean the body before any paint with soap and water.
I let it air dry and then I primer with the ruddy brown primer... Once that's dry, I mist the body with some water in a spray bottle and then sift my salt over it... A combo of sea salt and table salt....
Let this air dry and then I spray the satin paint for the body color over this...
I do mist coats until I get complete coverage.
I let this dry for a few hours since its a flat paint, and once its dry, I put the body under cold running water and using the toothbrush, lightly scrub the salt off and you will have something like this...
Now once that air dries, I take some of my acrylic paint and a cosmetic spong and lightly dab the sponge on the acrylic paint and using a paper plate, I dab the sponge on the plate until the sponge is almost dry. Then I dab the sponge on the body ( think dry brushing)... Less is more ... I use the acrylic colors as described above...
When done it should look like this....
Hope this helps a bit.... Ask any questions you have and I'll answer as best as I can for you...
