Hiding Foam Latex Edges

One of the keys to getting a great looking foam latex application is getting the edges right. Here's how...
After attaching the foam latex appliance with prosthetic adhesive, smooth the edges with 99% rubbing alcohol (avoid getting the alcohol in the eyes). If you still have a step down from the foam latex piece to the skin, you can mix up a little makeup "bondo", which is 50% prosthetic adhesive mixed with 50% cabosil, or translucent powder. Using the paste, you can smear a small amount onto the edge of the prosthetic and skin, filling in the gap. If you add too much, allow to dry and then apply a little 99% rubbing alcohol with a smooth brush to blend the makeup bondo with the skin and appliance. Be sure to allow the makeup bondo to dry. Next apply RMG (or castor oil followed by creme makeup) to the appliance. You'll be able to see where additional bondo is needed. Next, use a stipple sponge with prosthetic adhesive along the edge. The roughness will add realism. If done right, you won't see where the appliance ends and the skin begins. Have fun!
