The Test To Determine Which PPG Paint Covers The Best
All painted tested to determine which PPG paint covers the best was white semi-gloss paint without tint. With few exceptions adding tint improves coverage.
The applicator did not know what paint he was applying. Therefore, the name of the paint was on the bottom of each clear plastic container. After the applicator applied the paint, he wrote a number on the container to keep track.
Only after the judges evaluated all the paint did they know which paint grade they scored.
