EL paint is expensive, so it only makes sense to use the best equipment to apply it to minimise usage. We ourselves use RPS cups and the SATA Minijet 4400B RP for applying EL paint and clean the guns afterwards using the RCS Compact gun cleaner. As the system is made up of lots of layers requiring frequent material changes, this setup minimises the time spent cleaning the guns (under 30s for a material change).
