That is all a matter of prefrance dude. Check out Miva's post and you will see that he strips, but also the huge risk in it. I personally put a single layer of primer on the car. Like CW stated to me a couple weeks back, it gives you a blank slate so there are no supprises later down the road.
if you don't understand what payaso said above, heres some more clear words. He means, he only uses "easy-off" on his messed up blotched paint jobs. If hes painting over a stock body with the original paint, he'll just spray it with primer to make the paint lay down easier.
ah i see, yeah i was planning on painting a couple bodies soon,
i just got a bunch of new ones, (new ones to us canadians)
went down to florida, figured id pick some up cuz i never seen em before in our local RS, but i forgot to check for the NOS motor and performance parts
