    Then theres the old 2 pak (again with the k) paint. Which was an acrylic enamel or lacquer im not sure which that had an accelerator or hardener. Which isnt quite 2k because its not completely dependent on the hardener to cure.
    The system was kind of similar to using japan drier in oil based paint
    The pak thing really stumps me why the k
    Now that the k in 2k is clear to me . Thanks, Malky

    nm, i think thats a spelling people just sort of adopted after 2k became prevalent
    and seems to now be used interchangeably with 2k
    idk a lot comes down to common local community usage of terms.
    Like we often say waterbased when we mean waterbourne
    or people say acrylic for almost everything. what it really is depends on context.
    Gets confusing a lot of times

    World wide use of the k is probably so as not to confuse 2c with the temperature, can't have folks trying to freeze their clear in a moment of confusion.

    I thought 2 Pak was a dead rappero_O:)

    I know i kind of said this but on mini guns its generally roughly.;
    .5 or .6= at this size I treat it as airbrush so .6 is just wide area do it all size, nothing you cant run in it.

    .8= 1.2 or 1.3 full size
    1.0= 1.4 or 1.6 full size
    1.2= 1.8 full size.
    But they also arent as sensitive, trying to push primer through a .8 mini wont be bad like trying to push primer with a 1.3 full

    Just for reference

    this is actually great post. I was confused about the difference between mini and full gun.

    I will argue your stats above Robby,
    a lot of us use the LPH80 which is described as a 'compact' spray gun, the needle can be anywhere between .60 & 1.2 depending on the model.
    I have the LPH80 with the 1.2 set up.

    From what i've read the main difference between a mini/compact/touch up gun and a full size spray gun is the physical size of both the gun and the cup. yes full size guns will likely go up a bit in needle size.

    Unless you plan on spraying cars / walls all day then there really is no need for a full size spray gun.

    I think a qualified person such as @Shane1971 should have some input here.

    C'mon Shane, enquiring minds needs to know . . . . What defines a 'mini/compact/touch-up' gun Vs a full size gun ?

    Its kind of a loose reference, from experience I can say a 1.0 or a .6 can run any paint you want
    Just comes down to how fast do you need the mini to work.
    Kind of the same with the full too but it just becomes way more critical when youre shooting an entire car to have enough speed that the paints not dry by the time you come around to the other side.
    Priming a car with a 1.3 will put you past your dry times, it could take an hour to put a good layer on vs 15 min with a 1.8
    How fast you can cover a wheel with a .8 vs a 1.0, difference is seconds

    Shooting a door...ok now i need 1.0 at least

    Viscosities vs atomization is another factor but again not so critical with a mini, youre throwing less paint, so thinning it to spray is not so much an issue.

    Quick example
    Auto air calls for a 1.2 full size gun
    .8 or 1.0 for a mini

    So why dont they call for 1.2 in a mini if they run the same way?

    ah ok, i may have mis-read your post, i thought you were saying that a mini gun was of a certain size nozzle. . .

    Obviously smaller air cap, nozzle and paint capacity in the pot for touch up guns. I use them for small repairs on bumper bars etc so I can contain the paint and don't get over spray everywhere. And I use an Iwata w400 1.4 for bc / cc for larger panels and resprays.

    no just a sort of rule of thumb conversion for picking a nozzle size.
    Seems counter intuitive , like a mini should be more sensitive, but a 1.2 mini is only pushing like a 150mm pattern at 70ml/m where 1.2 full is pushing a 250mm pattern at 100 ml/m
    1.2 mini is dumping the paint on that little pattern while the 1.2 full is just dusting it.
    so for a mini to act like a 1.2 full it only needs a .8
    So they spray different.
