My flame red corsa has a few scratches and a break in attempt has put a hole just under the door handle unit. i quite fancy havin ago at rubbin these bits down, puttin a bit of filler in and priming myself. Whilst doing this i would like to de-lock the doors and smooth round the handle units like so:



Can anyone give me any advice on what to use and how to use it and info about the cost. A body shop would do the spraying, but id like to do the other stuff myself.

Cheers

Andy
