Blending automotive paint into an existing finish.
Once the area is repaired, cleaned, and ready for paint, using the chart as an example, mask off your paint area, extending it 3 times further than your repair area (back masking will make a softer edge). Spray your first coat of paint on the repair area extending into the step 1 area. On the second coat, extend it into the step 2 area. For the final coat you will need a blending agent such as Matrix MPB-500. Read the directions on your blending agent. You may need to reduce the blending agent. Mix the ready to spray blending agent with the reduced paint at a 1:1 ratio and spray the Step 3 area. If necessary you can lightly blend the edges with 100% ready to spray blending agent.
