The guys at PPG told me that the Omni line is not as good as the top drawer PPG paint in the following ways:

1) It does not cover as well as their top of the line paint.

2) It is not as durable as the good stuff

3) It does not contain as much of the UV blockers as the top of the line paint.

4) It does not contain as much solids as the good stuff.

For what we use the Omni paint for is great for our models---Our models are not going to be exposed to the elements nearly as much as a car will be.
