Spot Prime Filled Areas

What happens here

For areas where Bondo filler has been used, spot prime them with Zinnser B-I-N Shellac-Base Primer. This prevents potential outgassing (release of gases from the filler) or pinholes from appearing through the final paint coats. While some modern paints can be applied directly over filler without issue, it's a good precautionary step for a flawless finish.

Goal: Prevent outgassing and pinholes in filled areas.
