The 2.0 tip is too large for General Finishes High Performance Gloss when working with an Earlex 5500 sprayer. We recommend that you use a 1.5mm tip instead.
One of the causes of orange peel is the application of too much fluid and not enough atomization to break the product up into smaller droplets. It's similar to putting your finger over the end of a garden hose.
High Performance Gloss is going to be the most finicky of the sheens to spray. Both Critter and the Earlex devices are suitable but atomization can only be increased with smaller fluid tips or larger spray units
