What this video covers

Fairing a transom requires a systematic approach to identify and level high and low spots before painting. Applying a guide coat of primer reveals surface imperfections, such as pinholes and uneven areas, by highlighting where sanding blocks make contact.3:39 For rough fairing, an electric longboard reduces physical strain, while a rigid 32-to-34-inch manual sanding board ensures a flat finish for fine-tuning.5:53 When applying filler, pulling the trowel lengthwise across the surface—rather than across the contour—prevents the tool from following dips and ensures the filler bridges gaps.11:29 If the primer remains within its 24-hour recoat window, spot-filling pinholes with epoxy filler requires no intermediate sanding.18:27 After filling, sanding with 120-grit paper followed by three consecutive daily coats of primer creates a smooth, paint-ready surface.24:25 A dry fit of hardware, such as an outboard bracket, confirms that the transom surface is sufficiently flat before final assembly.21:43
