Good on you respraying a car that anyone else would consider a 'banger'.
I am also looking for a place that can replace rear arches (inner and outer) and a few other bits and give it a complete respray (mk1 MR2). Will be in the original colour.
That brings back memories, I had a white mk1 mr2 a while back and loved it!
The guy I recommended also does welding and put a sliding door bottom on my van, you cant see where the join was at all.
He is well worth having a word with and his prices are really reasonable. If you do speak with him, tell him Barry gave his details.
Good luck!
ps - he has some really interesting motors which evidence the quality of his work.
