    It normally says it on the can. But I roughly use half thinners, half primer/paint/clear and leave enuf room in the top to add more paint or thinners if necessary....I don't worry about proper measurements lol. That's why I got a mate to paint my wagz, would of turned out shocking if I had done it. :p

    One thing I always seem to stuff up is clear, coz if ya don't thin it out enuf it comes out like cobwebs....can stuff ya paint job up if that happens. I always spray on something b4 wat I'm painting, but sometimes it must suck through a thick bit....I think I just need to spend a bit more time getting it ready haha.

    half half sounds like too much thinners to me, i thought it was more like 25% thinners?
    best thing to do is go down to repco or somewhere that sells paint and read the instructioins on the cans if your can don't have any.

    depends what your painting with..

    i was told start with 50/50.. if its too thin add paint, to thick more thinners..

    using a stick or something you want it to just run nicely off it without to much resistance

    it diffrent for diff brands as for clear and colours too
    read the tin for the right mix ratio
    what is it? 2pac or acrylic


    most 2pac primers you look at ruffly 4:1:5<10% or 3:1:5<10%
    first number is primer part
    second number is hardner
    third number is percentage of thinners

    for basecoat in debeer its 2:1
    PPG deltron i think was 4:1 if a recall correct

    whats the brand ill look into it for you if you want




    on a side note you can add more thinners (20% max really) to your colour or clear to make it flow better but the higher percentage of thinners will cause it to evaporate more and dull the paint off when dryed
    only really do this if your skilled and able to put a good flat flow coat on
    my VL we did the clear with 20% thinners and my mate flowed it so well that it still looks like glass after its dryed. and it hasnt even been polished yet

    temprature effects the type of thinners hardner you use

    hotter days you use slow hardner and thinners to slow the evapration of them between the coats
    where on a colder day you use fast hardner and thinners to allow it to tack off between coats, quicker

    humidity should not effect the paint as you paint in a dry enviroment (booth)
    but if you take the panels out before they cool after the bake in cool weather they will asorb mositure and start to turn milky in the clear

    Should say on the tin mate, all paints are different so one ratio for one paint wont work with another.

    The paint we use at work is 2:1:25%

    Base:Hardener:Thinners

    But then we've got another type that is 1:1:25%

    Then another thats 3:1:10%

    they are all different.

    Hell, ones 2:.7:1.6 work that one out lol

    Be careful, you might mix it up and it might look amazing but it will either never dry or take ages to dry because you havent put enough hardner or thinners in.

    If its a well known paint your using, the manufacture usually has that sort of information either called "tech data" or "application guide" avilible on their website.

    Just for an e.g. heres a link for the tech data sheets for sikkens paint...
