Wax and Grease remover PPG's DX330 or more aggresive DX440,
But I would Never reccomend Fish Eye eliminator, as once you use it, its in your gun forever and will have to use it for every paint job you spray using that gun. I havent used that stuff in 20 years, its bad news!!!!!
Just make sure your vehicle is clean as hell before spraying color

And a 3m Desposable Charcoal Respirator , as if you use the catylist(hardner) it has Isocyinates, and will wreck havok with your lungs!!! They arent real expensive around 40 bucks i think , they come in a reuseable ZipLock bag.
