Available in 2 materials.
Black strong and flexible is gritty and very difficult to sand. Best if used as display AS IS only. If you want to sand the layer lines off, the ONLY way to do it is to coat the part in super thin set super glue. Then sand, putty, primer, and paint. Material is archival.
Black Acrylic is slightly more expensive, but is sandable like a regular model part
You need to order 3 (three) of these to make one complete set for your Moonbuggy
