Yup, just spent the morning and most of the afternoon cleaning them, (household products and nasty chemicals from the garage) then a blast with the random orbit sanding before filling the damaged areas. Tbh if it all goes horribly wrong I was going to pay for the refurb anyway, if it works a few hundred quid saved!
Just done a quick photoshop of the Golf with Zeniths, the jury is still out, opinions welcome -
