>>9668372I brush painted all of this with Tamiya acrylics, and it's a very light grey to boot, to make it extra challenging, and yet I didn't encounter any difficulty with it, and the result looks flawless to me. The only imperfections I can see is where I used sandpaper with too much grit or where I did a crappy job with the putty.
I also tried other brands in the past and I haven't noticed any difference (except for the matte/glossy "feel").
