Before we get into whether or not you can cerakote a polymer lower, let’s first briefly discuss what cerakoting is. Cerakoting is a method of applying a ceramic-based coating to metal, polymer, or glass surfaces to improve the aesthetics and/or durability of the item. This process was initially developed for use in the aerospace industry but has since gained popularity in the firearms world as well.
Now that we have a basic understanding of cerakote, let’s answer the initial question: can you cerakote a polymer lower? The answer is yes, but there are some things to keep in mind before doing so. First and foremost amongst these is the fact that rougher finishes, such as those created by stippling, will need to be sanded down before the cerakote can be applied. This is because the ceramic coating will not adhere properly to rougher surfaces.
Another thing to keep in mind is that it is important to use a high-quality polymer lower when cerakoting. This is because lower quality polymer lowers can be damaged by the cerakote process, which could lead to problems down the road.
Finally, it is important to note that cerakoting a polymer lower will add some weight to the lower. This is because the ceramic coating is heavier than the polymer itself. This is something to keep in mind if weight is a major concern for you.
With all that being said, cerakoting a polymer lower can be a great way to improve the look and durability of your gun. Just make sure to do your research beforehand and use high-quality parts to avoid any problems.
