Thanks for the replies.... I used Tamiya...XF-61_Dark Green...XF-52_Flat Earth...XF-65_Field Grey.
Then shot a coat of Future... a Raw Umber oil wash in panel lines. Then a coat of Future and Tamiya Flat Base in a mix of... 3 parts Future to 1 part Tamiya Flat Base. (As Per Swanny's tips )
Next time I may go with a 4 or 5 to one ratio. Came out mighty flat... seems to look ok though.
Maybe I got lucky with this camo job... It was a big improvment over my first model a few weeks ago. It was a Japanese Type 61 Tank.
Thanks, Jim
