I wanted to give you some of the basics of DuraCoat. It’s an involved process so I’m going to give you the bare bones basics.
The first thing to consider is what type of gun you have. If you are doing an AR-15 your “prep” work is less involved than many other firearms. The difference is the aluminum receivers and other parts. These are all anodized and receive much of their strength from that finish. It is extremely hard stuff. Therefore, never grit blast the anodizing off or you will compromise the strength of the receivers.
If you have an all steel gun we still have a couple things to consider. It all comes down to weather or not the gun is parkerized or not. Parkerizing and anodizing both are perfect base layers for DuraCoat so you want to keep both of them. If your steel gun is blued you will need to grit blast the old finish off. What you are looking for is a matte finish by media blasting or other finish (i.e. parkerizing). If you have a polished finish the DuraCoat has nothing to stick to and all your work is doomed to failure. Also,be sure before blasting that you plug both ends of the barrel. We don’t want to have a matte bore. Blue painters tape works well for this.
For the next several steps you want to have it hung where you will be coating it. From this point on never, never, never touch it with your bare hands. Doing so will transfer oils from your hands to the firearm and may compromise the finish in that spot. Always wear latex gloves anytime you need to handle the firearm until the project is finished.
Once every grain of your blasting media is cleaned from the gun (an air hose works well) you are ready for the next step in the preparation process. It’s time to degrease. You may do this with DuraCoat Reducer and a rag but there is a much more efficient way of doing it. While still hung up use what ever you have for a sprayer to hose down the firearm. There are other things you can use to degrease but DuraCoat Reducer is specially formulated to work with the coating. Anything else could also compromise the finish and allow it to chip, peal, and otherwise come off.
You are now ready to coat the firearm. I suggest using an airbrush or HVLP sprayer. You want to use light even spray across one direction and then the other. You may need to do a couple passes to get a good coat and that’s OK. It’s much better than getting too much in one area and having it run. I can talk about the coating process all day long but only experience will get you doing it right. That being said I will leave you with finished pictures of the pieces above with only this more to say, it is an involved process and any mistake can compromise the finish so try it at your own risk. I would still suggest taking it to someone qualified to do the job and make sure that person knows he needs to do the clear coat for added protection.
