Repaint a car body panel

Guide to repainting a car body panel

A sound car body panel with stable old paint can be refinished with careful cleaning, flat sanding, matched basecoat and a protective 2K clearcoat. This guide keeps the work focused on adhesion, colour control and a clean gloss result.

What do you need to repaint a car body 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.

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.

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.

Colour check before finishing

MP ColourCheck Spray helps confirm that the chosen shade looks right before the final gloss layer is applied. It is useful when the panel must match neighbouring paintwork.

How to repaint a car body panel

1
Clean and assess the surface

Remove wax, grease, dust and loose contamination from the panel. Check whether the existing coating is sound enough to sand, or whether deeper repair work is needed first.
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
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.
4
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 panel painting products should you choose?

Liquid spray-gun method

Choose the Mipa BC basecoat, BC thinner and CC 8 clearcoat method for a full panel where a controlled spray-gun finish is preferred.

Cleaner format

Use liquid silicone remover for larger panel wiping and the spray format for smaller areas, edges or quick local cleaning before sanding.

Technical details

Mipa BC basecoat is a two layer colour system and needs a compatible clearcoat for gloss and weather protection.
Mipa 2K HS Clearcoat CC 8 uses the matching HS hardener and 2K thinner specified for the clearcoat system.
Clean both before sanding and before coating, because wax or silicone trapped under paint can cause adhesion and finish defects.
The sanding block is included to keep larger panel areas flatter than hand sanding alone.

Practical suggestion

Do a small colour and spray pattern check before committing to the full panel, especially when the repaired panel sits beside older paint.
