Add stone chip protection to lower panels and wheel arches

Guide to adding stone chip protection to lower panels and wheel arches

Lower panels and wheel arches need clean scuffed surfaces, protected exposed metal and an elastic paintable stone chip layer that resists road debris.

What do you need to add stone chip protection?

Scuffing pad for lower panels

MP non-woven sanding pad keys existing paint, primer and edges without leaving deep scratches in areas that will receive protective coating.

Cleaning and degreasing

Mipa silicone remover in liquid or spray format removes grease, wax and silicone before sanding, priming or coating.

Epoxy primer surfacer

Mipa EP Primer Surfacer builds a fast wet-on-wet epoxy primer layer with active corrosion protection and direct adhesion on steel, aluminium and zinc.

2K epoxy primer filler spray

Mipa 2K-EP Primer Filler Spray is useful for smaller repairs and edges where a spray format is easier than mixing liquid primer.

Paintable stone chip protection

Mipa stone chip protection spray product gives an elastic paintable layer for floor pans, wheel housings, entry sections and exposed lower body areas.

Stone chip aerosol protection

Mipa stone chip protection spray in 500 ml format suits sills, wheel arches and spot repair areas where a controlled aerosol application is practical.

How to add stone chip protection to lower panels and wheel arches

1
Wash and inspect the area

Remove road dirt and check the lower panel, sill and wheel arch for loose coating, rust and old sealant edges.
2
Scuff the coating zone

Use non-woven sanding pad to dull the surface and feather the edge where the protective layer will finish.
3
Clean before primer

Remove sanding dust and wipe with silicone remover before any primer or stone chip material is applied.
4
Prime exposed metal

Use EP Primer Surfacer or 2K-EP Primer Filler Spray where sanding has reached bare or sensitive metal.
5
Apply paintable stone chip protection

Apply the Mipa stone chip protection product evenly, then overcoat later when the chosen finish requires body colour.

Which stone chip protection format should you choose?

Spray product for larger lower zones

Choose the 1 l spray product for broader sill, lower panel and wheel arch protection with controlled spray equipment.

Aerosol for smaller repairs

Choose the 500 ml aerosol for local stone chip repair zones, edges and smaller wheel arch sections.

Technical details

Mipa stone chip protection is overcoatable and intended for lower body areas such as floor pans, wheel housings, sills and spoilers.
The elastic protective layer helps resist stone chips, corrosion, de-icing salt and mechanical wear.
Mipa silicone remover is the cleaner named in the stone chip preparation method.
Exposed metal should be primed before the stone chip layer so corrosion is not sealed underneath.

Practical suggestion

Mask the upper edge carefully and keep both sides symmetrical. A clean edge makes the repaired lower panel look intentional after paint.
