Cooking Spray

• Cooking spray, normally used to enhance a skillet's anti-stick properties, is often used as a resin release. Cooking spray consists of oils that prevent other fluids from penetrating, meaning that anything that comes into contact with the spray will fail to stick.
  
  

Silicone Lubricant

• Silicone lubricants, long used to loosen stuck bolts and lubricate gears and other moving items, naturally repel and displace moisture. This includes those found in fiberglass resins. A thin coating of this lubricant will successfully protect an item.
  
  

Painter's Tape

• Painter's tape is specially designed to prevent thicker substances from penetrating through and around its edges. Painter's tape has a waxy coating, adding to the fluid-blocking properties of the material. This tape is best used for applications involving large, flat surfaces, where small crevices and cracks need not be protected.
  
  

Aluminum Foil

• As a kitchen staple, aluminum foil adheres to objects with little coaxing. Foil's shiny side naturally resists things from sticking to it, under most cooking temperatures. Given that fiberglass resins are used at room temperature, aluminum foil makes an inexpensive and effective release. Foil is best used where perfect surfaces are not needed, given its propensity to wrinkle.
