Mould lines and seams are the difference between a tidy model and a sharp one, and this little stick sorts them without you juggling half a dozen scraps of wet-and-dry. Three grades in one tool take you from knocking back a seam right through to a glass-smooth polish, and each section is colour-coded so you always know which grit you’re on.

Best for

• Cleaning up mould lines and seams on plastic and resin
• Feathering filler and putty flush to the surface
• Bringing edges up to a smooth, paint-ready finish

Work through the grades in order, 400, then 1000, then 3000, and a rough seam ends up polished and paint-ready with just the one tool on the bench.

Hard-wearing abrasive built for repeat use. Pair it with a fresh brush for a clean start to the next coat.
