Thanks for the feed back guys...
I decided to samd down the paint on the gt3 alittle because I didnt liked the end result of the tamiya yellow . So I sprayed 2 coats of Boyd Dark yellow and let the GT3 to dry... Here is how the gt3 looks like now.
The interior is almost finished as well, but it is nothing fancy as I am trying to learn about painting the body... I ll post some pics of the interior as soon as I get my camera back...
