One thing that can truly transform a cabinet is freshly powder coated parts.
A lot of people tend to just throw some spray paint on top of the original chipping and scratched paint/powder coat on pieces such as coin doors and corner protectors.
The problem is it never looks good. If you want to have them look decent, you have to remove what’s left of the original paint/powder coat. Unfortunately, the only good way to do this is with sandblasting.
Once you sand blast the rest of the paint/powder coat off the metal pieces, you can decide if you want to powder coat it or paint it.
Powder coat is better as it is more durable, and personally I much prefer the texture and feel that you just cannot recreate with paint. But not everyone has the equipment for powder coating, so paint is definitely better than nothing.
If you want to powder coat it, you will need two things; a powder coating gun. These can be gotten for under $100 and for simple stuff like this it will be plenty good. The hard part is an oven. DO NOT USE YOUR KITCHEN OVEN. As the powder is heated it releases gases, so once you use an oven for powder coating you should never use it for cooking again. Either get a cheap used oven off Facebook marketplace or there are a few DIY guides to build your own powder coating oven.
Once you have both of those, you will need to figure out what kind of powder you want to use. Personally, I use Eastwood powders as I’ve had some problems with cheaper powder turning out not great, which means you end up having to fully sand blast it back to bare metal, so I find it worth it to buy the better powders.
“Eastwood HotCoat® Black Texture Powder Coat” is what I used in this following photo. Its not the exact right texture for arcade coin doors, but it looks nice and has a good texture.
Once you have your powder, just simply use the powder coating gun to coat the sandblasted part with powder, making sure the entire piece has an even coating of powder without any missing spots or holes. Then carefully move the item to your oven and cook it with whatever powder you are using’s recommended cook time and temperature.
Once it cools down, inspect it for defects. If there is any, you can decide, depending on where they are, if it’s worth starting over, if it’s on the backside, it’s probably fine, but on the front it may be worth redoing.
