    pro17 graco what kit do I need to paint oil base paint?

    1 Answer | 
    Answer This Question

    The Prox 17 can spray non flammable oil based materials out of the box. If you would like to spray flammable oil based materials you'd need to purchase and install a lacquer conversion kit. If you have any additional questions please feel free to give us a call at 844-241-9499. Thank you, Graco Support Team

            Clean it out with water. Same as you do when cleaning out the pump at the end of the day or job.

              you just purge it thru as you prime the hose and gun assy. the pump saver fluid Is not an oil. it is a (non harmful) glycol base

              It's water soluble, just hook your garden hose up to the intake hose and flush it out until the water comes out clean.

                    I would say yes. if it sucks up and sprays paint it is a safe and useful product.

                        Goes on the inlet hose after you clean the system, place the pump armor bottle on the inlet hose set it in prime position let it run into you see the fluid coming out from the prime hose and turn it off disconnect the electrical cord, set it up into a spray position replace the inlet strainer and put a bag on the hoses for any dripping and use it every time to keep the system running like new it doesn't take alot of the fluid usually two ounces or less

                              You can use it between uses if you really wanted to. It’s essentially just going to lube the pump and keep your gaskets and stuff in the best condition they can be in. So to answer your question Yes you can use it if the down time is so short as it won’t hurt anything and can only help prolong the life of the pump and gaskets.

                                I would at least every other time. It helps just like antifreeze does for your water pump in your car.

                                  No, that shouldn’t be necessary for that short a time. But if you don’t use it for more than a few days, don’t forget to put some in.
