Sort of like the software guys blaming the hardware guys with computers when things go wrong
I haven't used createx in years but when I did it never caused a problem with temp tat. paint in the same gun, just clean it real well. Ideallllllyyyy it would best to have two guns one for t shirts one for temp tat's. Thats the only good use I found for aztec brushs, temp tat's they work great with the little color cups with the lids.
