  1. What is 'concours detailing' and how does it differ from standard professional detailing?

    Answer: It is an extremely thorough level of detailing aimed at achieving perfection for show car judging, including every surface and component of the vehicle

    Concours detailing is the most comprehensive and meticulous level of detailing, targeting absolute perfection of every surface including engine compartments, door jambs, undercarriage, and all trim for show car competition.

  2. What is the purpose of 'door jamb detailing' as part of a complete professional detail?

    Answer: Cleaning, protecting, and dressing the door jamb areas completes the vehicle's overall appearance and prevents the hidden dirt from contaminating the interior

    Door jamb detailing cleans areas that are highly visible when doors are open, contributing to a completely finished appearance and preventing road grime from being transferred to interior surfaces.

  3. When detailing a chrome-plated surface, which product should be avoided to prevent pitting or damage?

    Answer: Acidic-based products or strong iron removers that can etch or damage the chrome plating

    Acidic products and strong iron removers can chemically etch or damage chrome plating, causing pitting, dulling, or permanent surface damage to the decorative layer.

  4. What type of lighting is used by IDA professionals during a final inspection to identify any remaining defects?

    Answer: A combination of halogen or LED inspection lights at multiple angles, including direct and indirect (raking) light

    Professional inspection uses multiple light types and angles — direct and raking light — to reveal all surface defects including haze, high spots, and swirl marks that single-light-source inspection would miss.

  5. What specialty service is used to treat convertible soft tops to protect against UV damage and water intrusion?

    Answer: A dedicated fabric convertible top cleaner followed by a UV-protective fabric sealant or protectant

    Convertible fabric tops require a dedicated cleaner to remove mold and dirt, followed by a UV-protective fabric sealant to repel water and prevent UV-induced fading and degradation.

  6. What is the correct approach when a customer's vehicle arrives with active water leaks into the cabin before an interior detail?

    Answer: Advise the customer to have the leak repaired before the detail, as moisture will reintroduce mold and odor problems after cleaning

    Detailing a cabin with an active water leak will quickly result in mold regrowth and odor recurrence, so advising the customer to address the leak source first protects the durability of the detail work.
