On a narrow paint strip, applicator shape changes access and control. It should be tested without turning the comparison into a contest in hand pressure.
Confirm that the strip is suitable paint rather than plated trim or film. Photograph defects and protect neighbouring materials. A comfortable applicator on a flat bonnet may be awkward beside a window seal.
Pressing harder to compensate for a poor fit can produce uneven work and contact with excluded surfaces. Applicators carrying grit invalidate the comparison.
Select the shape that delivers the agreed finish with stable control. Record any defects retained to preserve the narrow painted edge, and use a separate preparation step if a curing coating follows.
