paint/primer question

[lt1chevelle]

well i was looking at the chevelle today to see how much body work still needs to be done i would say about 85% of its done the thing is i want to drive the car in the summer and really dont have the $ to pay for a paint job right now. the thing is when i was looking at it there are sand scraches in it. i was going to put about 3-4 good coats of feather fill primer on it and shoot some guid coat over it and call it good till the end of summer and the start to do the finale body work and prep work do u think the feather fill will fill in the sand scraches?
