So I got a bottle of Vallejo thinner delivered and tried practicing on spoons some more tonight. I got a really nice royal blue layer down on one. I was going for a bright yellow color on another, but the flow started getting intermittent and spitting. I think I thinned it out ok, but I probably just didn't mix enough. I'll try again tomorrow.
I *might* be getting the hang of this.
I'm going to find some insulation and tape to set up the spray booth ventilation. Since I use the room as an office as well, I don't want to rely on just a respirator and booth fan.
