I have 6 of these Maxum 11 guns for use with mostly automotive type paints but I don't spray cars with it. I use them with both Graco, Wagner and other turbines. Highly recommend them. The seals last forever even when the gun is soaking in thinners to remove old paint buildup.
This is one awesome roller. I've had mine for 15+ years or more. Just bought a second one for a big project. Added some extra duck bill seals and the roller splash guard. With the splash guard attached I usually don't even need a drop cloth. Easy to clean. Clean it well and put petroleum jelly on the seals and it will last. Well made, best investment I ever made. I use it whenever I paint.
