    Ok, before lock down I thought I got stocked up on everything I needed. Turns out I forgot to buy thinners. But do I need it? It doesn't mention it in the mixing guidelines in the data sheet below. GenRock 2K and hardener IMG_20200415_162953.jpg

    Does seem unlikely especially with 1.3 tip

    Surely you could still pick up some thinners in current times?

    I suppose you could do a small trial mix, should be obvious just by looking at it if too thick

    That TDS should include ratio for thinner or viscosity cup details. You have super fast hardener there and it isn’t listed as suitable for that paint on that TDS.
    Can you ask the supplier about the thinner.

    Ok, used a 1.4 tip, no thinners. Was actually quite close to the thickness I would have liked it. Went on ok and quite a good finish. Couple of runs on one panel but that's more down to my inexperience with my new gun/ bad lighting / being a novice.

    Thanks for the help folks

    Well spotted. I didn't notice this. This is what the paint shop gave me. It's seemed to be tacky within 10 mins as per data sheet so hopefully all is well in the morning too.

    Not using thinners actually improves curing gloss. On most stuff but not including primers you get a better gloss and the shine doesn’t drop no where near as it would with thinners added. If you think of it this way, thinners is like a foreign body where the drying of the paint just wants to expel it as fast as it can therefore knocking off a big percentage of the shine. You’ll also find it’s now easier to polish it too as there is less dullness to bring back up.

    I was told to add something like 30% thinners to the mix. I think I have a gallon of the stuff sat here if you’re anywhere near stafford.

    ETA. Just noticed, Scotland....

    That does make a lot of sense. It came straight out of the gun like a mirror which is a relief

    I used the Genrock Ford Black and the H200 hardener on my suspension, and used a dash of thinners, it worked out perfectly.
