Cerakote Torture Tests the Clear Coating for Aluminum [VIDEO]

Cerakote has published a video showing torture testing of their MC-5100 clear coating for aluminum. They applied the Clear – Aluminum coating to half of an aluminum tank surface leaving the second half uncoated. Then they applied various chemicals (drain cleaner, de-icer, bug cleaner, wheel cleaner, diesel, and gasoline) to these two surfaces, tried to leave marks with a permanent marker and even shot the tank with a shotgun (rubber slugs). The results are really impressive. You can watch the described and other scientific testing procedures in the torture test video embedded below.


Another video that was published earlier, demonstrates the self-leveling properties of the Cerakote Clear – Aluminum coating.


Below you can also find the description of this particular coating ( quoted from the company’s website).

Cerakote Clear – Aluminum

Item: MC-5100Q

MC-5100 Cerakote Clear – Aluminum has been specifically engineered for performance on all common alloys of aluminum, including magnesium alloys. Common applications include Polished, Brushed, Raw & Anodized Aluminum used in Architectural, Automotive, Industrial, Consumer Goods and more.

  • Easy to apply, Ready to Spray, Direct To Aluminum
  • Simple Dawn Dish Soap & Water Preparation
  • Tack free in approximately 1 hour Air Cure (Full cure in 24 hours)
  • Preserves true aluminum look while protecting against oxidation & dulling
  • 100% Inorganic Formulation is completely UV stable. Will Not Yellow or Haze
  • Unparalleled adhesion, chemical resistance, UV stability and hydrophobic properties on all alloys of aluminum, including Magnesium. (See TDS for details)
  • This coating excels in outdoor applications.

As seen in the description, it is possible to apply the Clear – Aluminum coating to anodized aluminum which should allow to apply an additional layer of coating onto your standard anodized aluminum parts (e.g. AR-15 receivers) while retaining their original color. This is my assumption based on the description of the product. If we have Cerakote gurus among our readers, please correct me if I am wrong.

    Cerakote is a relatively soft coating that doesn't wear well and has poor lubricity, cerakote a rifle bolt sometime and see how well it runs. It's used because it's cheap and colors match better than anodizing, especially across parts of different composition. At the end of the day it's glorified paint. You can put it over anodizing but it typically does not stick as well, unless the surface was bead blasted rough before anodizing. There are a laundry list of coatings for Aluminum that do a much better job in protection and wear resistance, Type III hard anodizing, DLC, IonBond, etc. You can almost watch uncoated Aluminum oxidize, put it up against a type III clear hard anodizing and see how it does.

      @Tom Type III isnt so much of a coating, its a controlled oxidation. And considering the process to remove it for re-anno is to coat with lye or sodium hydroxide (drain cleaner) I doubt it would fare better against the first "test" which was the only one in this case that mattered.

      I wanna see it against mercury, and calcium / magnesium chloride.

    Would be interesting to see the same test repeated with a quality clear coat rather than the CeraCoat...
