3. any segestions how is this car should look with body kit,wing(what kined of wing or body kit should i use)?

to strip paint use castrol super clean. No body makes a body kit for this car as far as i know. So, you'll have to create one yourself.

They do make bodykits for the Q45. Check various Japanese VIP style manufacturers like Junction Produce, Auto Couture, Fabulous, etc. The Q45 is known as the Nissan Cima in Japan, so look under that. Aoshima makes various VIP-style addons for models (wheels, wings, exhausts), plus complete models with the forementioned type of body kits.

Here's the Aoshima Q-45...
