There are many ways to get rid of old paint, primer and rust. You can use elbow grease, abrasive materials or chemicals. You could get it all scientist with electrolysis. You could learn to weld. Or you can blast it all out with an abrasive sandblaster. Luckily, you don’t have to put a ton of money into it either when you can use a gravity-fed blaster gun.
Welcome back to Nice tool! This series is going to take a slightly different direction. The frequency of your Cool Tools will no longer be just once a week. Instead, I’ll feature awesome tools when I find them. This may mean more than once a week, or less often.
Most importantly, this series exists and continues because you, the readers, use some really neat gear to fix your cars. So keep sending those suggestions. Lalita and I have both purchased tools from this series that we may not have had before!
Now back to the task at hand. As a resident of the Midwest, rust is a constant problem. Part of the reason why rust gets to the point of becoming holes is that getting rid of it can be quite a pain. You may scrub and scrub the rust spots then repaint, only to find you haven’t done a good enough job and the rust has returned.
It’s even worse if the rust has progressed beyond a few bubbles or larger than a small area.
There are other mechanical ways to get rid of rust like needle scalers, sanders, grinders, wires and even scissors. Another option that seems out of reach is sandblasting with abrasive media. If that sounds strange to you, it’s also sometimes called sandblasting. However, sand is no longer fashionable as a medium to use for removing rust and paint. Today we know that exposure to respirable crystalline silica found in sand can cause real serious respiratory problems.
Other types of sandblast media can be gravel, walnut shells, glass beads, plastic beads, etc.
The world of media blasting is huge with a bunch of different ways to do the same job. If you have individual parts, for example, you can use a blast cabinet to clean them. You can also use an abrasive pressure blaster pots for projects in your garage. But what if you don’t want to buy and set up a kit for a quick little job? Hemmings people to offer an alternative: a gravity-fed gun that connects to an air compressor tank.
As the name suggests, this tool is quite simple. You attach your air line to the gun, set your pressure, then pull the trigger. Media is gravity fed from the hopper and into the stream and onto the project.
See one in action at simple little life on Youtube:
People seem to use them for motorcycle frameshard to reach areas body and more. These little guns have also been around for decades and have become cheaper over time.
There are a few caveats with this tool. It is not as powerful as other forms of blasting. This small hopper also empties very quickly. However, these gravity-fed guns can be purchased very cheaply, making media blasting accessible to people who only use the tool a few times. Comments because these little guys seem to be good even for the super cheap Harbor Freight models.
We can have them for $59 for a brand model or about $20 for a generic model.
It should also be noted that you must wear protection when using this tool, even when not using sand. You don’t want media in your eyes or lungs.
