Primer??

Ok this is the first tiem i used primer so do i primer every little thing or just the body??
Also what filling do i have to do?? My model is a Tamiya XJ220 and its looks pretty well made..
Do i fill the joints with putty??

u don't have to prime everything, but i, prime the body, chassis, and interior tub...


U do'nt have to fill the joints, unless they r GAPING holes.... but if its a tamiya kit, it shouldn't be bad...
