Yeah, that's why I was asking, how long they last between pumps and roughly how many panels they cover......I wanted to use it to apply Koch Chemie Protector Wax so I assume it doesn't have to be a foaming sprayer.certainly the ones I have tried seem only good enough to do the wheels before giving up, ive gone back to pressure washer attachment cause i usually find ive missed a bit in the arches.
I think the IK ones have a Schraeder valve on them so you can use an air compressor rather than pump them, but I guess that doesn't mean they last any longer between re-pressurising them.




One end on each sheet blown.
