I've only ever tried customing before once.
And at the time I used those cheap little paints that come with stuff like
paint by numbers. What I ended up with was a funky looking
grimy feeling action figure with a rough rough paint job. Or maybe
I used oil paints.... Meh, I was 14 and never once looked at a tutorial.
The paints I have now are not model paints, but I've never custom painted
a toy since last time.
Now I am an artist(student) so the paints I have are these:
"Windsor and Newton Galeria Acrylic" paints (named since I can't link)
They may not be testers or the other brands mentioned, but they are acylic.
Would they be sufficent?
The only way to know is to paint with them. Just keep your brush damp (not wet, just damp) with water while painting and use lots of thin coats. Clean your brush every few minutes, or better yet, have a cup of water nearby and everytime you go back to get more paint, dunk the brush in the water to get rid of the paint on the brush and start with fresh paint.
Thanks for the info
