Paint repairs
Before carrying out paintwork repairs, clean the vehicle thoroughly using either a steam cleaner or high-pressure 
washer. 

Wash locally repaired areas using a mild water-mixable detergent and wipe them clean with solvent, immediately 
before paint application.

Ensure that damaged paintwork which has led to exposed metal is abraded until the metal is clean, extending beyond 
the area of the original damage. Treat the bare metal with an etch phosphate to remove all traces of rust and to provide 
a key for new paint coats. Re-treat the affected area using either a separate acid-etch primer and two-pack surfacer 
or an integrated etch primer/filler, and follow with a two-pack paint system. Treat those surfaces not receiving paint 
using an approved cavity wax, following paint operations.
