@Kerry Beal I agree with you. I have suffered long enough and finally breaking down to buy an HVLP.
@Jim D. Thank you! That's a really good idea. I know that HVLP gun is going to use a lot more cocoa butter; but I'd like to limit it. I know this has been assessed several times in the past. But it's such a big investment. I've also been thinking about the gun that I tried in Melissa's class. I've been shopping around and I was able to find the SATA 3000 for about $500. She had limited overspray and it was able to do splatter very well. (As for the overspray, it may be a bit deceiving because of her big and powerful spray booth).
I like the idea of using air compressor because I can use the compress air to dry my molds after washing. I have the Iwata coming in a week. I'll let you know how it goes. I think what impacts my decision is the amount of effort I need to put into my DIY spray booth. I figured that the more overspray, the more powerful the motor for the spray booth needs to be. I'm leaning to making the collapsible version that @Pastrypastmidnight had at her home kitchen.
Let the spray gun quest continue!
