I'm going to bump this up, since I have a question about Tamiya paints.
I bought 5 bottles the other day, because I wanted to try some better paint and they had it in the colors I was looking for. Everyone says these are supposed to be thicker.
The paint seems to be much thinner, instead of thicker. When I go to apply it my brush just wipes it off and it won't cling to the surface, it seems way too watery. I wonder if it is the brush I'm using or if I am completely missing something and I just suck at using them. Anyone have any tips on how to use this stuff correctly?
I've never experienced this problem with tamiya paints before aside from the Metallic colours, which tend to run a little, but not too much. Depending on the colours, the thickness can actually vary (From my experience, the flat colours are more thin), but even the thinner ones I've used can stick onto to plastic exceptionally well. One thing I find helpful is to "bathe" your figure first. SOmetimes a figure can accumulate oils and such from your fingers and just plain being exposed; and in some cases, being packaged. You can reduce figure oilynedd by rinung the figure with warm water and using a dish soap to clean it a bit. That should help make it stick.
EDIT: The thing about tamiya paints, also, is that sometimes there's a thicker layer of paint on the very bottom that cannot be mixed by shaking at all. Use a paint mixer or even a chorstick or toothpick to scrape that thick bottom layer out, mix it in a bit and then shake it again. Maybe that could help.
