tried da sander with 150 grit and its taking the surface rust off, theres no pitting or serious rust on this truck, i sanded to the black,
i read about sandblasting to bare metal, is this necessary? Is my da sanding and removing surface rust okay? whats the hardest grit i should use without damage? Then do i still need etching primer or can i use a rustoleum primer before painting the frame?

It depends on what you are going for. If you are doing a show truck, then strip to bare metal and use etching primer or have it powdercoated. If you just want to use something like POR15 or Zerorust, then all you have to do is clean the rust off the surface and paint it on with a brush.
