Mmhm, I think just call wagner or check places like spraygundepot or even eBay for an M15 to 1/4" adapter and with it you can run a standard whip no problemI picked up a Wagner Control Pro HEA 150 for our reno, it works great, and I'm trying to add a hose whip, but the threads aren't standard and it's been tough to find one, does anyone know the thread type?
