Here's the secret to getting a perfect blending of the new color with the old. PPG produces a color blender that we sprayed on the edges of the clear to essentially melt everything together. Then we followed that up with another coat of clear, this time applying it out a little farther. After one more application of the blender on the edges of the last coat of clear, you can put the spray gun away. Be sure you understand all of PPG's instructions when using the company's products. All that remained was to follow standard color-sanding and buffing procedures and we were good.
