i use tomahawk classic mostly, never had a single break in the gun or barrel. It shouldn't matter what paint you use though it should run fine through ur ion
I've never had a problem with paint in my ion, where my friends who use Angels can have nightmares with paint out of the same box as me. I believe the ION is quite lenient on paint.
yeah iv used site paint before and that goes through fine although flys bit wonky, i use proto paint always now or the combat 68 balls off planet they really good
