Wash and preclean the entire panel using 3M™ Professional Panel Wipes 34567 and 3M™ Adhesive Cleaner 08984.
Compound the entire panel using 3M™ Perfect-it III™ Fast Cut Plus Compound 50417 (and 3M™ Perfect-it III™ Extra Fine Compound 80349 if a dark colour) to get the panel back to a freshly painted appearance.
Sand out the defect using a 3M™ Hookit™ Abrasive P180 or P320 76mm Disc. (Always start with the finest grade possible). N.B. The use of 76mm discs helps to minimise the size of the repair area.
Apply a stopper if required and sand using 3M™ Hookit™ Abrasive P180 / P320 Disc or Sheet. N.B. Using a 01908 Handblock with the abrasive disc will help keep the repair area smaller than using a traditional block.
Sand around the repair area using a 3M™ Trizact™ 75mm, P1000 Blending Disc 50413.
Enlarge the area further using a 3M™ Trizact™ 75mm, P3000 Fine Finishing Disc 50415.
N.B. Remember to think small, the completed sanded area should be no bigger than a A4 Sheet.
After the clearcoat is fully cured, remove any defects using the 3M™ Microfinishing P1500 260L 76mm disc 00907 or the 3M™ Trizact™ A5 Disc 50079 on the 3M™ Finesse it™ Sanding Block. The 3M™ Trizact™ P3000 Grade 76mm Disc can be used on the blend area to reduce the overspray.
Compound using 3M™ Perfect-it III™ Fast Cut Plus Compound 50417 followed by 3M™ Perfect-it III™ Extra Fine Compound 80349 to blend the new and old paintwork.
