Hobby's pretty good. Costs about RM6 per bottle. As for the booklet saying that u need 13 colors, its both yes and no.

Yes in the sense that that's probly the most exact colors that they use on the model as per in the booklet. No as in, you dont really need to get all that 13 colors, just get the primary colors, such as:
- Black
- White
- Red
- Blue
- Yellow
- Brown
- Silver
- Gray

That should allow u to pretty much mix all sorts of shades that's needed. You'll find that you'll use up the blacks and whites at a rather fast rate compared to the other colors too.

Nup. ToyCity will only get u Tamiyas, which basically sucks big time and costs a bomb too. U'll need to visit those like XL, or those shops at Berjaya Times Square.

If you're new to painting, then I suggest that you start off by using acrylics. Make sure u get the right types. Acrylics (water based) from Mr Hobby r the ones with the flat caps, while the lacquers (thinner based) r the ones with the mohawk looking caps.

Get a spray can of Mr Surfacer 1000 as well for the priming work to be done before you start painting. Later on, then you can invest in an airbrush, where its better to use thinner based lacquer paints.
