It was a decent rec ball paint, can't remember the brand, certainly much better than the diablo heat I was using. I've messaged the owner on facebook to find out.
As Stu says it fired fine through a5's (generally hard on paint), an Etha, the sandbaggers GSL, and a hammer 7 (hardish on paint), some kind of spyder clone (hard on paint) and I don't think any one was having barrel breaks despite a very damp day.
It broke well on people as well and had a nice thick bright filling (unlike the thin dark water in the heat I was using).
Pop along - it was a fun day.
