blending paint on autobody repairs

This is memike on my wife's computer !!
2 stage, clear coat, if you are repairing a ..... lets say a fender and the damage is close to the front, cover the entire car and paper the fender except the small area to be repaired .
base coat the small area ( lets say 3 coats) then uncover the fender, tape it off and water cuff/sand (2000 wet sand paper) the tape line down smooth where it was taped off for repair, prep/clean the full fender and base coat the front again and just blend back to about half the fender or panel your are blending, next coat back away from the fender an extra 10 inches and fog 2/3'es of the fender aiming away from the back of the fender, when you are happy with coverage clear that fender and hope the color comes close to matching is how I did it back in the day, then un cover the next panel (door in my case) buff and shine the door if all looks good let it cure and wash the car and hope it matches., I did do this a few times but it's 12 or more years ago, the clear coat will help with having the same texture/smooth finnish over the blending area. good luck and I hope a new paint tech will jump in here soon to let us know what he/she would do.
