...and I think
Tamiya paints are the best thing that's happened since sliced bread!
It all depends on the technique you're using and how you go about painting. Myself hate "pure" acrylics since they never seem to dry and I can't be bothered to wait an hour - let alone 24+ hours most "pure" acrylics take to dry!
My
Tamiya + iso in 50/50 mix dries in seconds and I never have to stop and wait for colour changes. It dries faster than it takes me to change paint in the
airbrush.
I also never user primer. I use XF-69 in 70/30 mix (70% paint, 30% iso) as primer and it's ready for base coat as soon as I've cleaned the
airbrush and changed the colour.
This way I can paint a whole kit in one session - from primer to varnish. I sadly have to wait for the varnish to dry but that's ok because I'm normally a bit tired after primer, base, masking, paint, masking, paint etc etc and eventually varnish.
I tried to use AMMO paint on my Takom King Tiger and that ended in a disaster. It was user error though but when corrected it took 5 days just to lay down the base coat - and that's way too slow for me.
Brush painting
Tamiya is much harder and here I prefer AMMO and Vallejo and I'm using different thinners depending on what I do, and if I'm painting a 2:nd or 3:rd layer, but for
airbrush Tamiya is the best I've used so far. MRP is something I will try when they add more AFV friendly colours.
Mig Jimenez shows that his paint obviously work since the stuff he's creating is often wonderful - but he lives in a lot warmer, and dryer, climate than I do so he can use "pure" acrylics without worry. I can't unless I leave the model next to a radiator for 24 hours, and often it's only touch dry and not fully dried. That can take many days...
It's a good thing we have so many different paints out there to suit all of us!
