Step 1: Materials
Clay (non-air drying)
Acrylic Finish Spray (matte, gloss, satin ect...)
Curved blade tool
Shoe Polish (brown or black)
For the base:
Plaster of Paris
Sandpaper (rough to fine grit)
Primer Spray Paint
Step 2: Molding Emblem
Roll and knead the clay to get rid of any air pockets and make it more pliable.
Roll the clay into a ball and press your item into it. Gently twist to release from the clay.
Vaseline the USMC emblem (or whatever item you choose to use) making sure to get into all the little crevasses.
Center the emblem into the impression in your clay and press gently, yet firmly. Try to keep as even a pressure as you can.
When removing the emblem be very careful not to smear the impression in the clay.
Check your mold and make any adjustments or touch ups you need to.
Note: Make sure your mold has a flat bottom for the next step.
Step 3: Casting Emblem
I used Amazing Casting Resin:
Measuring equal parts solution A and solution B, stir for approximately 30 seconds and then pour into the mold.
It sets in about 5 minutes, but I leave it for about 10.
Remove cast from the mold and clean up the edges with an Xacto knife, or other sharp blade of choice.
An old toothbrush and some dish detergent work great to get off any excess clay.
