For achieving a refined, polished surface on scale RC projects, the Mr. Hobby GSI-MT308 waterproof sandpaper is a reliable choice. This kit contains four sheets of #1500 grit designed for delicate detailing and final surface prep before painting.
The #1500 grade is perfect for the last sanding stages where control and a consistent finish matter most. Use it on plastic bodywork and painted panels to remove minor imperfections while keeping edges neat. Its waterproof design supports wet sanding to minimise dust and deliver a cleaner result.
Each sheet resists tearing during repeated passes, so you can work longer without replacing material. The sandpaper adapts to plastics, painted surfaces and light metalwork, giving hobbyists flexibility across typical modelling tasks.
