So i started off with a nerf maverick, retails for about 13$ canadian, pretty commonly used in blaster and steampunk prop designs.
I stripped it apart completely ( to make the painting more even, that and i plan to reassemble it in "hopefully" functional condition.
As I opened it up, I did take pictures of the internals to see how everything was put together.
Next, i went with a base coat of gloss black Krylon. I used to use krylon for touch ups on airsoft guns. I used very light coats spraying from about 1' away. Every few hours going back and doing another coat.
Next step, weathering. I bought a bottle of matte grey nail polish, and used a drybrushing technique on it, all over the main components of the blaster. Because nail polish dries so fast, I did have to work quickly to make sure it spread out well.
Next I went back to the gloss krylon, and at a distance re sprayed the pieces very very lightly, to lessen the impact of the dry brushing, it ended up making the weathering look a bit more natural.
Next I plan to use a matte clear coat to seal everything in, help prevent further wear and chipping. ONce thats done, ill be putting it back together.
Hopefully after doing two or three of these things, ill be able to modify one with sound, and an led. Im thinking of using a blade plug and a red led unit in the barrel. Only time will tell if i can make this work.
