Alloy wheels and caliper finishes
Ask which parts will be removed, how surfaces will be prepared and what the finish includes. Cosmetic refurbishment is not a substitute for assessing cracks, distortion or other wheel damage. Caliper work must not interfere with the braking components; use a competent specialist and agree the scope in writing.
Window tinting and road use
For vehicles first used on or after 1 April 1985 in Great Britain, the windscreen must allow at least 75% of light through and the front side windows at least 70%. Existing glass and added film must be considered together. A film percentage alone does not demonstrate compliance.
Paint correction, detailing and coatings
Ask the provider to inspect the paint before recommending polishing or correction. Clarify which defects can realistically be improved and which need repair. For ceramic coatings or paint protection, obtain written care instructions, exclusions and any warranty conditions; do not assume a coating makes paint damage-proof.
Dechroming and changes to appearance
Clarify the material, edges, expected upkeep and removal process. Ask whether the proposed work needs to be declared to your insurer and whether it affects any applicable vehicle warranty. Photograph the condition and record the agreed finish before work starts.
