SMART Repair

SMART repair is a cost effective technique and can be utilised when the area to be repaired can be contained within the area of an A4 sheet of paper.

SMART Repair Process

Full SMART Repair Process

Damage Assessment

Access the position, size of damage and colour for suitability to SMART repair (THINK SMALL).

Surface Cleaning

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.

Surface Preparation

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.


Mask out the surrounding area to be painted using 3M™ Soft Edge Foam Masking Tape Plus 50421 and 3M™ Taped Masking Film 05967 with Scotch® High Performance Masking Tape 3434 07895.

Primer Application

Apply the primer following the paint company recommendations. Overspray must be kept to a minimum to keep the repair area as small as possible.

Primer Sanding

Sand the primer using 3M™ Hookit™ P500 and /or P1000 76mm Abrasive Disc.

Paint Application

Apply the basecoat to the primed area using 3M™ Mini Paint Preparation System (PPS) again following paint company guidelines. N.B. Apply the basecoat from the outside in to keep the area small and the overspray to a minimum.

Once the basecoat is thoroughly dry, carefully Tack the area using the 3M™ Tack cloth Aqua 50401. Apply the clearcoat to the basecoat area and then fade the edge away using the blending agent.

Paint Rectification

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.
