Agreed. Although I do manage to clog my H with Vallejo Model Air every time I use those paints. But I think that was more because Vallejo seems determined to clog any airbrush it goes through, at least any airbrush that I’m using. I respect Vallejo for their massive color range and I use them a lot for bristle-brush painting. But, man, there’s something about those paints that doesn’t like me because no matter how much or how little I thin them they simply refuse to perform as advertised through an airbrush. And I should have listed my experience with them as another modelling headache.
Overall, BTW, the only real difference I’ve seen in my own painting experience with the Paasche H vs double action airbrushes is that the double actions seem to control overspray better than the H is capable of. Other than that the H does an equally good job as the double actions on the overall paint job and, even better, is significantly easier to quickly & thoroughly clean at the end of a session.
I don’t have an overspray problem with mine at this point. I was painting right up to the edges of the insides of some 1/24 automotive wheel assemblies last night and the edges are still completely bare so they can be glued. I mostly use the #1 needle and then use a pack of PostIt notes to get the spray pattern and pressure dialed in to where I want it for a particular job. You can also fine-tune the pressure just by how far down you press the plunger.
