ok update.....Now that the mechanicals have been fitted we hang the doors,gaurds,headlights and bonnet on.We then get all the gaps right then disassemble the car again....this time we leave the door hinges on the vehicle.Then we dry rub the car with 240 grit paper taking extra care where our repairs were to shape the vehicle nicely.Then we dust the vehicle over with black dust from a 3M guide coat power sponge,this allows us to see where we are wet sanding which we do with 400 grit wet.Then the car is dryed off and wet rubbed again using 800 grit wet
