Before a compound touches the paint, a depth gauge tells you how much material you have to work with. Readings across each panel reveal thin spots, repainted areas and previous heavy correction, so you can choose a gentler pad and product combination where the finish is already thin.
- Rechargeable power means no hunting for spare batteries during a long correction job
- Take readings in a grid pattern on every panel and note any that stand out from the rest
- Unusually high readings often point to refinished panels or filler, which is useful during pre-purchase inspections
- Record readings on a worksheet before and after correction to document the work for the client
