Sorry for not replying and updating lately. had a problem with the internet connection.
Now lets get back to class.Dry brushing can make your Gundam look like it's made of metal.And for me thats cool hehehe
You can use any chrome silver or silver marker or paint for the effect.For me this is the one.
I would just use a little bit of paint.Use more if the result is not visible
Using the brush move it in a circular motion so the paint is equally spread on the tip of the brush.Some people would usually wipe the extra paint on a tissue until just the right paint is left but i don't do that because i would just wait for the paint on the brush to dry a little bit(Wait around 5-7s)then i would start brushing but the disadvantage of this technique is,you have to put a little extra force while brushing and you have to brush a lot longer.At least little paint is wasted
After.Not really visible right so more paint should be use.
Let's move to the body
Dry brushed his cannons and arms but since the color of his arms is light grey its a little bit hard to see
Heavily dry brushed the body
