Guide to repairing stone chips on a front car panel

Stone chips on a front panel often expose primer, metal or older colour edges. Clean preparation, local primer filler, matched colour and clearcoat help stop the chips from standing out after the repair.

What do you need to repair stone chips on a front 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.

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.

Clearcoat edge solvent

Mipa 2K HS solvent supports the transition zone on smaller clearcoat repairs. It is useful where the new gloss layer needs to flow cleanly into an existing finish.

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 stone chips on a front car panel

  1. 1
    Clean and assess the surface

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

  2. 2
    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.

  3. 3
    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.

  4. 4
    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.

  5. 5
    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 stone chip repair products should you choose?

Primer filler for exposed chips

Use Fast Filler Spray or 2K Acrylic Primer Filler where sanding has exposed substrate or left small chip depressions.

Full panel or local repair

Use the BC and CC 8 liquid method when the repair area is broad, and the aerosol method when the repair is truly local.

Edge finishing

Use Mipa 2K HS solvent only where clearcoat edge transition work is suitable for the chosen repair method.

Technical details

  • Front panels collect chips from road impact, so loose paint edges must be removed before primer.
  • Primer filler helps level small chip marks before colour so they do not remain as dark dots under clearcoat.
  • A clearcoat stage is needed over basecoat for gloss and exterior protection.
  • The sanding block supports even feathering around clustered chips.
Practical suggestion

For many small chips close together, treat the area as one feathered repair zone instead of filling every chip as a separate dot.
