Solid colour does not automatically mean single-stage
A solid colour can use a single-stage topcoat or a basecoat with clearcoat. The colour’s appearance alone does not establish the repair process. The existing system and any previous repairs matter.
What a two-stage system contains
In a typical arrangement, the basecoat provides the colour and clearcoat lies over it. How a scratch is treated depends on whether only the upper surface or deeper layers are affected. Polishing does not restore missing layers. Actual condition and previous repairs must be considered.
Why a third stage can change the work
A three-stage system creates its appearance through matched layers, such as a ground colour, an effect coat and clearcoat. Application and transitions can affect the visible result. Colour matching and the required working area need to be planned accordingly. Not every effect colour uses the same system; the particular vehicle matters.
The damaged area is not always the paint area
A small scratch can require more extensive treatment depending on its position and colour. Blending into nearby areas may be needed for a suitable transition. Attached parts, panel edges and earlier repairs also affect the process. Comparing a price only by scratch length tells you little.
What does this mean for your enquiry?
You do not need to identify the paint system yourself. Give us the model and paint code if known. Photos in even daylight and details of known repainting help. We clarify what is missing for planning and whether an inspection is needed. Do not sand or polish the area to make the photograph seem better.
Is metallic paint always more expensive than solid colour?
That distinction alone cannot determine the total work. Damage, surface, system, area and preparation need to be considered together.
