PRECISA BLUE SPOTTING PASTE
It is an intense and uniform BLUE spotting paste, ideal for surface inspection and locating high spots during scraping operations or contact points between parts to achieve assembly precision (molds, bearings, valves, gears, and other components with tight tolerances). It is used by bringing the reference surface (after the PRECISA® SPOTTING PASTE has been applied) into contact with the surface being checked; the colored parts highlight the zones that need to be scraped.
PRECISA RED SPOTTING PASTE
It is an intense and uniform RED spotting paste, ideal for surface inspection and locating high spots during scraping operations or contact points between parts to achieve assembly precision (molds, bearings, valves, gears, and other components with tight tolerances). It is used by bringing the reference surface (after the PRECISA® SPOTTING PASTE has been applied) into contact with the surface being checked; the colored parts highlight the zones that need to be scraped.
PRECISA YELLOW SPOTTING PASTE
It is an intense and uniform YELLOW spotting paste, ideal for surface inspection and locating high spots during scraping operations or contact points between parts to achieve assembly precision (molds, bearings, valves, gears, and other components with tight tolerances). It is used by bringing the reference surface (after the PRECISA® SPOTTING PASTE has been applied) into contact with the surface being checked; the colored parts highlight the zones that need to be scraped.
