No you can not use your standerd airless pump with the rhino type coatings.yes it is easy to do with the right pump for polyureas,some pumps are airless based systems and have fixed or adjustable ratios and then there are the slower more portable systems like the vortex and many others that are similar to the vortex but they all require a special gun with two material lines where the two components are mixed @ the gun or through disposable static mix tubes on the gun.for quick dry rhino type coatings.
