Summary of Building Prototypes Dan Gelbart part 6 of 18 Coatings

00:00:00 - 00:20:00

In this video, Dan Gelbart demonstrates how to create a prototype using a variety of powders. He first mixes together some of the powders and then splits the mixture into small pieces, which he then dumps into a mold. The powders become liquid and quickly solidify, creating a prototype that is filled with dents and cracks. Gelbart then lets the prototype cure for a minute or two before sending it off to be finished.

• 00:00:00 In this video, Gelbart discusses how to prepare a surface for painting, how to sandblast it, and how to paint it. He also discusses the importance of surface preparation, and how a bad paint job can be due to a weak bond between the paint and the metal.
• 00:05:00 Sandblasting and heating can be used to prepare surfaces for bonding or painting. The first method is more effective, but the second is simpler.
• 00:10:00 In this video, Gelbart demonstrates how the surface energy of a material can affect its ability to retain water. He also discusses how to prepare a surface for an operation, such as bonding or coating.
• 00:15:00 This video demonstrates how to use electrostatic painting to fix defects in metal. The powder is heated until it melts, and then is sprinkled into the defect. The melted powder fills the defect, and the paint seals the area.
