Re-lacquering may be needed because the sun has affected the lacquer sometimes bleaching or cracking the veneer and in extreme cases causing it to go opaque or milky.
This is quite common on Jaguar XK8 XKR models registered around 2000. The effects of the elements can make the panels and the associated problem look worse than they actually are. Leading one to believe the whole panel including the veneer has been compromised when in actual fact it goes no further than the lacquer. Once removed the veneer returns to its natural clarity and colour.
Often panels do not require full blown restoration or even re-veneering, but simply need to be stripped and new coats of lacquer applied.
A typical example of this is the Rolls Royce Silver Shadow, Rolls Royce Spirit, Rolls Royce Silver Spur door capping’s and dashboard panels. These can be stripped back to the original veneer using specialised heat processes and a great deal of care.
The veneer can then be sanded to regain its original colour, sealed with polyurethane and recoated with polyester lacquer as originally used by the manufacturer. The polyester lacquer is then flattened until it can be polished to a high gloss finish.
