Preval and ProResist…

[ThisIsMyFirstRodeo]

Note to self: Just don’t.

Basically my experience was from attempting to spray a 50% dilution. The resist started gumming up into the “white glue”-type sludge, clogging the nozzle. 
Another sign of a mistake is the freeze warning on the side of the bottle. And the propellant in the cartridge is well below freezing as it’s released. I was doing my best to use short bursts to prevent the nozzle from freezing over, but who knows how successful that was. 
At least I’m only down a cartridge and some time, though what did spray seemed to lay down surprisingly even. Perhaps an airbrush is still a possibility for application, but definitely not with the Preval system. (It did work wonderfully for my dye though!)

Learn from my experience so you don’t have to make the same mistake 😉

And may you never burn your bacon…

Sometimes things work... 🙁

Don't dilute Resolene with isopropyl alcohol for airbrush work, it curds up. Use water.

Will do, and thank you for your input. I did use water to dilute, but maybe there’s enough of a difference between Resolene and Pro Resist to give different results. I haven’t worked with Resolene yet to test/experiment… The wife did give me her airbrush though, so I’ll probably set the Preval down. 
But I have started to cut the resist with water instead of using full-strength, and I cut my dye to various dilutions with 91% iso alc. I have yet to put it through the airbrush though, so I’ll find out soon if I should or not. 
 

General question for the audience though: 
Has anyone sprayed NFO? And how were your results?

I think you will be get better results with the airbrush. My basic procedure is oil / dye / oil and I don't use a top coat for my projects.

You will need proper air pressure to drive the dye into the leather. From what I have seen on youtube people are using pressure settings in the sub 20 lb pressure range and then the dye is basically a top coating.  Probably because most people are painting model figures/cars/nails/cakes/etc. I use a 30 lb pressure setting and am now moving up to 40 lb when applying the dye with multi coats in different directions to get a more even dying which I apply after the oiling process. My basic process is oil/dye/oil.

Here is a link to two of my topics on airbrushing.

I don't use NFO and can't speak to it's application with an airbrush. I use JoJoba oil and spray it on without any dilution.

As always, you come through with some great insight.
And yes, the airbrush is a light-duty cake decorator, but maybe it’ll give her a gift idea. After all, Christmas is coming 😉

I think (hope?) I have finally made my case to spend the extra $15 on the Pro Dye to not stress over the potential for bleed, and to skip the topcoat step and save time. Regardless, I still want to explore the airbrush application method. My initial project resulted in a halfway decent sunburst, so I’m excited to see what I can do with a little experience.

I prefer to use the single action airbrushes and the two main ones I use are the very inexpensive suction style at $21 CAD rather then the gravity feed type. Load up the dye bottle, push the button and you are spraying. If you are planning on using it indoors a regular compressor can be very noisy when it has to recharge the air tank and really is overkill for an airbrush.

Keep in mind the dye will darken and spread in the leather after a few days. So you have an initial photo of the project so take another photo a few days down the road for a comparison.
