Can I Use a Rust Gun on My Old Metal?
Are you a beginner in the rusting industry and would like to learn how to use a rust gun? Are you trying to find ways to get your work done faster and safer so you can save time and money? Then read this. You will learn what it takes to clean a rust gun, the safety measures to take when handling a rust gun and some recommended lubricants for use with your new tool. Armed with this information you should be able to start working right away.
Before we get started let's talk about how to use a rust gun safely. You probably have seen or heard of the term "barbless" which is used to describe a rust gun. What exactly is a barbless gun? It is a power tool that has no bbs (brass wires) in it and instead has an electric coil that is used to drive the bb's by energizing the power input and driving the wire round the barrel. With no bbs, it is much easier to control and remove rusted areas of metal quickly. It can also improve your overall safety when using your tool as you won't have to worry about getting your fingers burned from the rusted areas touching other parts of the gun.
Now that you have an understanding of what a rust gun is and where you can safely operate one, let's talk about how to remove rust from your project parts. Before you do anything, close all doors and windows to keep the corrosive chemicals out of your work area. You want to use a paint-safe chemical cleaner that does not react with the rust on your metal parts. Some of the most common choices include muriatic, oxalic and petroleum based cleaners.
When you have finished applying the cleaner, turn your attention to your rusted area and begin brushing in a circular motion. Make sure to wear eye protection and gloves so you don't accidentally scratch yourself. Do this on both surfaces of the rusted area. You may need to repeat the process several times to properly get rid of all traces of rust. To finish off your brush, use a high quality rust sprayer to completely cover the rusted area.
If you are concerned about the smell of the gun cleaning chemicals, you will find that many products on the market today will eliminate rusting without emitting a bad odor. These sprays act much like an aerosol spray and will cover any rusted surface with a thick layer of paint. Many of the better brands available today also have a lubrication feature built into the sprayer which keeps the gun working well for a long time. This is especially important for starting and stopping the spray. Keep in mind, though, that the rust gun is not meant to be used outdoors where there is a chance of the chemicals coming in contact with the metal surfaces.
Another thing to keep in mind is that these guns are only effective if you use them on areas that are rusted. If you try to clean the gun while it is not rusted, then you are likely to damage the metal. The best way to clean the gun is to use water and soap, combined with a small amount of household bleach. Do not use ammonia-based cleaners as they can permanently damage the metal.
After spraying your rust gun, let it dry and buff the surface of the rusted area. The goal here is to get rid of as much excess moisture as possible. Next, you should sand the area down to bare metal. After this, apply rust primer on the rusted surface, if applicable. Finally, apply an exterior coat of paint to give your vehicle the look of a freshly restored rust.
These guns are not suitable for all types of metals, such as steel, copper, and brass. If you use these guns on these metals, it is likely that the surface will become pitted. You can avoid this by using a different type of rusting product or a different type of gun altogether. Another downside is that they are expensive compared to other types of guns. They can run into the thousands of dollars, though their high cost does not mean that they are not worth the investment. They are also a lifetime investment, which will save you money in the long run.
