Guide to repairing small dents and repainting a car panel

Small dents need shape correction before paint. The panel should be cleaned, filled in thin layers, block sanded, checked with control spray, primed and finished with matched basecoat and 2K clearcoat.

What do you need to repair small dents and repaint a car panel?

Cleaning and degreasing

Mipa silicone remover in liquid format and Mipa silicone remover spray remove wax, grease and silicone before sanding or coating. Clean again after sanding so dust and fingerprints do not sit under the new finish.

Body filler shaping

Mipa P 99 Multi Star fills and finishes metal repair areas before primer. It is useful when one repaired panel needs a level surface rather than only a scuffed existing finish.

Fine filler finishing

Mipa P 85 PE fine filler closes smaller scratches, pores and shallow surface defects after the main repair shape is formed. It helps prepare a smoother base before primer filler.

Colour and surface checking

MP ColourCheck Spray helps assess the colour and finish before the final clearcoat decision. Mipa Control Spray helps reveal sanding marks and low spots while the surface is still easy to correct.

Primer filler base

Mipa 2K Acrylic Primer Filler and Mipa Fast Filler Spray build a sandable base over repaired or keyed areas. They help level small scratches and sanding marks before the colour layer.

Basecoat colour layer

Mipa BC Ready Mixed Two Layer Basecoat creates the matched colour layer on the prepared panel, while Mipa BC Thinner VDG supports the spray viscosity required by the BC system.

Clearcoat protection

Mipa 2K HS Clearcoat CC 8, Mipa 2K HS Hardener HS 25 normal and Mipa 2K Thinner Normal V 25 form the gloss and protection layer after the basecoat has flashed.

Aerosol colour and clear method

Mipa Mix Acrylic Spray Paint and Mipa 2K Clearcoat Spray give a spray can method for smaller local repairs. Use this method when aerosol application suits the repair size and finish expectation.

Flat sanding support

The MP sanding block keeps hand pressure even across the repair area, panel edge and primer surface. A flat block helps avoid waves that become more visible after gloss clearcoat.

How to repair small dents and repaint a car panel

  1. 1
    Clean and assess the surface

    Remove wax, grease, dust and loose contamination from the dented panel. Check whether the existing coating is sound enough to sand, or whether deeper repair work is needed first.

  2. 2
    Shape the repair area

    Apply the correct filler only where the panel needs shape correction, then sand with a block so the repair feathers into the surrounding paint without a hard edge.

  3. 3
    Sand and refine

    Key the surface evenly and remove sanding dust before coating. Use guide or colour checking where it helps reveal scratches, low spots or uneven preparation.

  4. 4
    Prime and sand the base

    Apply the suitable primer or primer filler for the exposed substrate and repair depth, then sand the dried primer until the surface is smooth enough for colour.

  5. 5
    Apply the colour layer

    Apply the matched colour in controlled coats over the prepared base. Keep the repair edge soft so the new colour can visually blend with the surrounding finish.

  6. 6
    Finish with clearcoat

    Apply the compatible clearcoat system after the colour layer has flashed. Let the coating cure before polishing or putting the panel back into normal use.

Which dent repair products should you choose?

Main filler and fine filler

Use Mipa P 99 for the main shape and Mipa P 85 for small pores or final surface refinement before primer.

Liquid or aerosol finish

Use the BC and CC 8 liquid method for a full panel finish, or the aerosol colour and clear method for a smaller repair zone.

Checking before primer

Use control spray during block sanding so low spots can be corrected before the finish coats are applied.

Technical details

  • Filler should be built and sanded in controlled layers rather than buried under heavy primer.
  • A sanding block helps keep the repair contour flatter than fingertip sanding.
  • Primer filler gives the repaired zone a uniform surface before colour.
  • The clearcoat system should only be applied after the colour layer has flashed as required by the paint system.
Practical suggestion

View the panel from several angles after guide checking. A small dent that feels smooth by hand can still show a wave once clearcoat adds gloss.
