    I am interested in airbrushing designs into computer parts, and for this I need some paint that will resist over 100 degrees C and is non conductive. I've been using rustoleum automotive enamel spray paint which does the job, but you can't do any detail work with spray paint so I need an airbrush equivalent.

    Also, can you just use any old clear coat spray paint when you're finished airbrushing?

    Hi DIY tech, they are specialist paints and I suggest contacting paint suppliers for specific details. Others may know but the airbrush specific paints are unlikely to take that sort of temp well. In terms of what you put over top, always, always, always refer to what the manufacturers recommend. If you are putting the clear over the top of the high temp stuff you will need the clear to be able to take the heat as well.

    Pop along to the intro section for us as well and say Hi.

    Just pass your paint from the can to a jar with a drink straw, it's very easy and you don't waste any paint in the process, and then you can use it with the airbrush!!:thumbsup:

    If you're going to decant spray paint to an airbrush I would suggest you use appropriate thinners, a mask, ventilation and a cheap knock off brush- I wouldn't run anything through a $$$$ airbrush that's not designed for an airbrush and expect consistent result.
    Would an artists brush do the detail you have in mind?
    An airbrush isn't a tool you can pick up and do minute detail with, without a significant amount of practise.

    Yes I could use a paintbrush but I couldn't find any normal paint that would work for my purposes so, I figured I'd be able to find paint similar to the spray paint that I could put through an airbrush. I won't be using anything that isn't meant to work well in a brush so don't worry :p

    I could try contacting a specialist I suppose. I wouldn't be using clear coat on the parts that need to resist temps, only on the outside of the case. I'll follow the directions, thanks for the tip.

    I suppose I could if I had no other choice and a crappy brush, but I don't want to risk it with a nice brush

    With the appropriate thinners it's possible. What brush are you thinking of using ?

    And what are you painting in a pc that going to get to 100C ? Most CPU shouldn't be over 60C

    Yeah 100C is more of a worst case scenario kinda thing. Hottest thing I'll probably be painting is the GPU.

    Thinking the iwata eclipse looks good to get?

    You can reduce most any paint and get it through an airbrush. Problem with paints designed for spraying in a gun (rather than an airbrush) is the pigment is larger. The reduction to get it to a sprayable consistency means there is too little pigment. It might work but is more likely to be filled with woe. Try chatting to the guys at Coast Airbrush or somewhere like that. They might have some specific ideas. Bonnets in cars can get very hot but not normally the 100 degrees hot.

    Id be worried that painting system critical parts like GPU's would reduce the capability to expel heat, therefore making them run even hotter and die a premature death

    Yep that's what I do with certain paints, make sure you let it sit for a few minutes to gas off before you put it in your airbrush and wear protective equipment. I'm not sure about clears that can take extreme heat, but for outer case you should be fine. 2k auto clear is tough stuff, but there is a learning curve to spray it and its nasty stuff.

    I guess I could try it if I don't find anything specifically for airbrushes. Just clean it really good right after

    Yeah, lacquer thinner usually cleans up most paints. Key word is most. Definitely check product info to see what will thin it and/or clean it up.

    Yup, don't spray 2k (or any other 2 pack paint) WITHOUT the proper protective equipment for your AND your neighbors. Check where you live for possible limitations on spraying them as well. 2k is baked at about 60 degree c and as I recall is not designed for operating temps of 100 degrees.

    So you are painting VOID on all the parts LOL
    Most GPU have a shield which directs air flow which unless you have the entire system overclocked to the max and a poor cooling system will it ever hit 100F degrees .
    But they is a lot of paint on the market for things that go up to 100000 F and can be used through an airbrush but they come with a high price tag.

    Things like GPU , PSU are never really seen even with a plexi side on the case. unless you have a complete plexi case .
    Just saying most want the outer part of the case painted which any paint will work .
