These guns appear to be fairly nice, The 1.7 should spray heaver bodied materials. Usually 1.7-2.0 is what they reccomend for High Solids Primers.

FMX I am not familuar with the finex Iwata gun , but I think its their small touch up gun for spraying small areas and doing light paint work, ( dont hold me to that though)

I got to demo the new 3M paint gun and all I can say is WOW, they did an excellent job on the design ! This gun will make alot of bad painters good, it really lays out base metallic and pearls very nice. It doesnt leave a hard overspray edge when spraying spot jobs when blending out, leaves a smooth soft edge. I would buy one but I have so many now I dont use all the ones I have now ........LOL

Oh by the way they are going for $420- $480 dollars. If you want a gun that will really help on laying down a nice job, i would highly reccomend the 3M gun in a 1.3-1.5 for an all around base/clear/sindle stage gun.
