Shelled out $200 for a topcoat gun and it made zero difference on my last job

I bought this pricey Iwata spray gun thinking it would finally give me that glass-smooth clear coat finish at 2 AM after a long day. Spent Saturday morning re-shooting a hood for the third time because the result looked exactly like my old $80 gun. Same orange peel, same dust nibs, same everything. Turns out my prep work was the real problem, not the tool. I should have put that cash toward a better respirator or a longer deadline. Anybody else blow money on gear thinking it would fix a skill issue?

$200 for an Iwata sounds about right but honestly even expensive guns need the right air pressure and fluid adjustment. I ran into the same thing with my first HVLP, spent weeks blaming the tool before realizing I was just laying it on too thick too fast. Did you check your viscosity or just send it straight out of the cup?

...and I'm gonna push back on that a little, @the_stella. I actually think expensive guns cover up more mistakes than they fix. If you're laying it on too thick with a $200 Iwata, you'd be doing the exact same thing with a $40 Harbor Freight special. The gun isn't forgiving bad technique, it's just making bad technique cost more. Air pressure and fluid adjustment matter way more than the price tag, and honestly I've seen guys with cheap guns spray better than guys with high end stuff because they had to learn the hard way. The viscosity thing is a fair point but if you're thinning paint right for the gun you have, the gun itself shouldn't be the bottleneck. Feels like people blame the tool because it's easier than admitting they skipped the basics.

Yeah but I gotta disagree a little with milessmith on the forgiving thing. I've used both cheap and expensive guns and a good gun does let you get away with more if you know what you're doing. The problem is most people don't check their pressure at the cap or run a viscosity cup before they mix. I had this exact same issue with a Sata gun I bought used for $150. First few jobs looked like garbage until I realized my compressor was putting out way more moisture than I thought. A water trap fixed half my problems and a cheap digital pressure gauge fixed the other half. People drop cash on a fancy gun but skip the $40 worth of stuff that actually makes the gun work right.
