flaking paint

To me it sounds like adhesive problem. You might be trying too blend too far. Did you sand past the area that you want to blend? If it ain't scuffin it ain't stickin therefore its flaking back off.

More details are needed, just what is flaking? Is it the primer from the metal, the base from the primer, the clear from the base? how was it prepared, what materials were used, etc.

First I would clean the panel with a good wax and grease remover then water block the edges with 400 grit wet or dry sandpaper until the edges or gone then apply 2 coats of 2K primer then water block with 600 grit then you should be ready to paint

If you have true flaking, paint separating from primer then you may be chasing your tail. You may have an adhesion problem and any repair may be only temporary.

yes thats exactly the solution i was looking for Rag top bird,i have bought a gallon of quick line panel wipe!will the panel wipe degrease?i have 2 sheets of 600 and 1200,picked up 4 red 3M scotch pads also to help degrease the whole car as i plan to paint the whole car as the factory paint job has came up in patches,like i mean all the way to the metal!no rust,just a small tiny dry bit of base coat left on the steel in the patches where the paint has flaked off with age!

flaking paint

It's mopar factory paint, true fact any dodge (mitsubishi) i have seen has had paint issues,might just need to strip it clean and put a new paint job with good paint, like dupont. Or else like 302 z28 said, you will be chasing your tail.
