The Quikks stuff would probably just be a rubbing compound followed by a polishing compound or possibly ultra fine wet and dry like 2000 or 4000 grit but no good if the lacquer has already gone.
A localised repair should be ok as long as the lacquer can be taken back to a point where the solvent wont lift it when they try and apply a primer or bar coat. i use a 2 pack filler primer as when it goes off it seals the area as some primers, or if you just try and apply the base coat that is 50 % thinners, it will just pickle up the edge of the old lacquer and look ****e, then its just a case of compounding the whole area, wet flat the primer, re apply a base coat to blend into the area and then re apply lacquer back over to blend in with the compounded area and they can use a fade out thinners to blend the old and new lacquer.
Then when the 2 pack lacquer has properly cured they can compound and polish the whole area if required.
