These 4 bolt fishplates are designed to fit in the web of G Gauge 332 size rail. They should be glued with a waterproof glue if used outdoors in a garden railroad.
If using ACC (Super Glue) then two coats of glue may be required with the White Natural Versatile Plastic is it is a laser sintered nylon powder. The first coat of glue will be absorbed into the sintered nylon and the second will bond well.
The White Natural Versatile Plastic will take paint well as it will be absorbed into the surface of the fishplate.
This item is available in both White Natural Versatile Plastic (previously called White Strong and Flexible - WSF) and Smooth Fine Detail Plastic (previously called Frosted Ultra Detail - FUD) acrylic material.
