A dash repair would prob cost about the same as your quoted replacement costs and would you be happy with a repair in the long term?

I've seen many dash repairs where people fill and respray the dash. I just need mine sprayed. I've a scuff that show the colour underneath. A White/grey colour. Just wondered if anyone knew of dash repair kit or replace.
