Painting and weathering continued today!
I took the box and suit outside to get them dirty. Let’s start with the box! It’s very clean, but we need to fix this.

Using a variety of weathering sprays and flat black paint, I misted different colors on the box. I focused on the upper corners and edges. Result!

Next, I worked on Mono’s suit.

I applied a mist of flat black spray paint to darken the pants and shirt, and some brown weathering spray on it all, including the jacket.

My son was super excited to put things on when I bought it all inside! He just put on the jacket and mask for now.





Next, I worked on painting the key. I applied another few coats of Modge Podge to the key, but I really wasn’t happy with how slowly it was filling in some of the paper lines underneath. I decided I could do better with several coats of PlastiDip. Here you can see the initial coat of black.

After a few coats, here’s what it looked like when it was dry.

Still not happy overall, I decided to take a chance and spray the key all over with metallic gold PlastiDip. I’m so glad I did! One coat wasn’t bad. I thought I could do better, so I kept going by applying a few more coats of black PlastiDip and let it dry.


Then I hit it with a thick coat of black Hammered finish paint. This made it super shiny!

I was getting frustrated with how some of the paper lines were still visible. So while the Hammered paint was still wet, I applied a dusting of metallic gold PlastiDip, going thicker and thicker with the coats. The PlastiDip dries fast, and it began to create a very cool crackled effect that I was not expecting! I moved it into the sun while I painted to help accelerate the effect. Here’s the result:


I am thrilled with how this turned out. It looks like beat up old metal now!


I will probably add some more black and maybe some brown to further age the key in some spots. It’s so awesome when something not expected turns out much better than I could have hoped for!

















Hi – I’m making this costume for my daughter, and I’m unsure what type of paints to use to “weather” the box for her mask? If you have any suggestions, I’d be so grateful!
You can easily apply a light misting of black and brown spray paint to create the weathering. Keep the nozzle of the can a good distance away from the area where you’re spraying so the paint goes on very lightly. Less is more, and you’ll want to apply very light layers for a nice effect. 🙂
You could also apply dirt. Yup, straight up dirt! Or even black and brown eyeshadow (applied with a large makeup brush. Seal the pigments onto the surface with a light misting of matte clear spray paint to keep the color in place.
If you have access to an airbrush, using black and brown tones would work equally as well. Feel free to let me know if you have other questions! Happy to assist if I can. Good luck, and have fun!
Hello 🙂 This is amazing. Trying to pull together a last minute Mono costume for my son. Where did you find that perfect coat?
Thanks! I picked it up over on Amazon. https://www.amazon.com/gp/product/B091YCG1DB/
