If you're planning on powder coating your car's brake calipers, there are a few steps you need to take first in order to prepare them. First, you'll need to remove any existing paint or coating from the calipers. This can be done with a chemical stripper or sandblasting. Once the calipers are stripped down to bare metal, they need to be cleaned thoroughly with soap and water, then dried completely.
Next, the calipers need to be primed before powder coating. This will help the new coating adhere better and also prevent rusting. You can use a self-etching primer for this step. Once the primer is dry, you're ready to powder coat!
When applying powder coat, it's important to get an even coverage so that the finished product looks professional. Use a fine-tipped brush or spray gun for this step. After the powder coat is applied, it needs to be cured in an oven at 400 degrees Fahrenheit for 20 minutes. And that's it! Your calipers are now ready for their new powder coat finish.
