Guide to restoring and painting classic car body panels

Classic car panels often combine old paint, previous filler, bare metal spots and shape correction. A careful repair order with stripping, epoxy primer, filler refinement, basecoat and clearcoat keeps the restoration work controlled.

What do you need to restore and paint classic car body panels?

Old paint removal

Mipa Quick Paint Stripper and Mipa Paint Stripper Spray help remove unstable old coating before the panel is rebuilt. Keep stripper work away from plastics and rinse or neutralise the surface before priming.

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.

Epoxy primer protection

Mipa EP Primer Surfacer with the matching EP hardener and EP thinner gives direct adhesion and corrosion protection on prepared steel, aluminium or zinc. It is the stronger primer method for bare or sensitive metal.

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.

Rust repair support

Mipa P 50 glass fibre filler supports stronger filling on rougher damaged areas, while Miparox anti rust spray helps protect cleaned local metal before the repaint build continues.

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.

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 restore and paint classic car body panels

  1. 1
    Remove weak old coating

    Strip or sand away failed old paint, cracked filler and loose edges until the panel has a stable foundation for restoration work.

  2. 2
    Clean and assess the surface

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

  3. 3
    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.

  4. 4
    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.

  5. 5
    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.

  6. 6
    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.

Which restoration products should you choose?

Metal protection method

Use EP Primer Surfacer with the matching EP components where classic panels expose steel, aluminium or zinc and need a protected rebuild base.

Filler sequence

Use fibre filler only for rougher damaged zones, P 99 for main shaping and P 85 for fine finishing before primer.

Surface checking

Use control spray and a sanding block during the restoration work so waves and low spots are found before gloss makes them obvious.

Technical details

  • Old multilayer paint should not be trusted if it is cracked, lifting or soft under sanding.
  • Epoxy primer helps protect exposed metal during slower restoration work.
  • Different fillers should be used by repair depth, not piled together without sanding and checking.
  • The final colour and clearcoat should be applied only after the repair surface is stable, sealed and smooth.
Practical suggestion

Classic panels reward patience. Correct the foundation before colour, because extra clearcoat cannot hide old waves, trapped rust or unstable filler.
