Update: Took the parts into the body shop with me today, did a lot of work on them....Flatted the bumper and filled a few bits that had chips, used a rotary with 400 grit pads to sand it right down....Then used 800 grit to provide the key & finally used scotch pad to get it ready to be sprayed.
Applied primer to the bits that were filled, should be in again tomorrow to work on this further.
I should have got some progress pics tbh, I'll get some tomorrow
Also sanded down the door handles ready to be sprayed, the other bits I've put on top of the over for later
When I get time I'll dig out the old pics etc & make a progress thread
