I cut out the main shape of the gun and mounted it to a large sheet of cardboard.
Next I glued on some of the smaller elements which were made from thin crafting foam.
Next I took the gun outside and gave it generous layers of filler primer.
While the filler dried I hopped on the computer and played with possible coloring and designs.
I decided I wanted my ray gun to be purple. When the primer dried I gave the gun a light sanding and fixed a few small spots.
And then I gave the gun a first coat of purple paint.
After several coats of purple acrylic paint the gun is still looking too dark...
...so I went out and brought some purple spray paint.
That did the trick. When it dried I started to draw on details using some silver paint markers.
Thanks for reading!
UPDATE: Many of you have been asking for my templates and a complete list of materials I used.
The templates I am happy to share. Send me your email address in the comments and I'll send you the templates when I can. As for the materials, here's what I used:
Also, after years only one person has sent me back a picture of their finished project. So I'd like to thank Marin for sending me this picture. Good job Marin!
