    Plus I hate electric for not allowing me to sloppily apply water for wet sanding.

    I guess pneumatic wouldn't work in my case :(

    Yeah it kind of sucks being limited to electric, but it sure beats manual ......well....kind of.....sometimes.

    Idk if you saw the edit to the dynabrade comment ....

    Make sure to do that little tip about working an electric..... Should be easy to train your self to do since you aren't used to pneumatic.

    If not you'll be out a lot of pads and likely create massive gouges in your work too.

    I must have put about 35 hours a week on a dynabrade for a year or so. Then like 10-15 for several more years. They aren't the very fastest but they are insanely durable.

    Doesn't really matter for you but just had to say that.

    I would have few test runs so I get used to new tool. I was hoping I can pull of with some small pneumatic one, cause I seen few of them claiming to use like 200 liters of air, but to be honest I don't mind going electric, cause I don't have experience with either. I would mind if I screw my self with buying something which is crap though, or even worst, buying something awesome and then my compressor wouldn't pull enough and I would just look at the tool and cry :D

    I have no doubt you could run a 2 inch pneumatic on it.
    Panels would be a little wavier but just as shiny, take a little longer, use paper faster.

    If it were me I'd probably go that route.

    I think even finest wool would give bigger mark, compared to 5000. The question is why to use it? And to use it for the applying... IDK. What's the reason?

    I will experiment with pneumatic when I have my big compressor ready. But that's not going to happen soon.
    Wet sanding of the clear might be good, but I could only say if I'd try. Rupes has good range of pneumatic tools besides the electro and the brand is pretty affordable.

    I looked at this somehow https://www.rupes.com/product/rh353/
    But my current compressor won't feed it. Though the tool's air consumption is low.
    There's smth to choose from them http://www.rupes.com/category-product/pneumatic-tools/pneumatic-tools-sanders/ :)
    Now they have even 9mm orbit! Real beast ! I can only imagine how fast it cuts the putty etc.
    Haven't been to their site for a few years, they have more tools now. Two types with different suction, one without the suction - cool! But the question is where to get the compressor that would feed all of them:)


    This one looks exactly like pneumo sander https://www.mirka.com/cs-CZ/Mirka-CEROS-625CV-150-mm-zdvih-25-MIM6252011/
    Has brushless motor and works at 22V.

    Remembered one thing I had done some years ago:)
    75 mm (3") polisher. Made on the base of Chinese knock-off of Makita polisher. Makita is also pimped;)
    That's how you can upgrade your polisher.

    Interesting, if it's got enough torque it might even act like pneumatic........ Hmm

    DA sander is orbital eccentric sander? I noticed in automotive they are talking about DA sanders.

    It is not the same.
    The 2nd is a double action DA.
    If you press too hard, the rotation stops.
    It is the least agresive and the easiest to keep under control.

    Depends, technically yes kind of as you've seen but DA has become almost ubiquitous for anything not strictly rotary. Even with manufacturers, so you really have to look hard sometimes to see what is really what.

    Even Erwin said no but then showed you a rotary eccentric was a DA.
    The second one is labeled rotary eccentric

    Orbital is orbital ... I don't think I've seen orbital eccentric. It would be constantly driven and rotated but have an elliptical orbit.


    So anyhow, another one of those things where terms can get wildy crossed.

    Actually I messed up too.
    Random action orbital is a DA.
    I'm not even sure what orbital eccentric is but it could well be s synonym for rotary eccentric which is a synonym for DA or random action.

    Still orbital is orbital.
    It is fixed it's orbit but doesnt spin under power like many buffers.

    DA kind of bounces around.

    now I am even more confused lol

    But I did check online and I made a mistake. At my place they sell orbital or eccentric.So there is not orbital eccentric :) So not one of those is DA right?

    I'm pretty sure eccentric is if they just say eccentric.
