SIG Rhino-Hide
Rhino-Hide foam wing covering is made from wood fibres compressed under high pressure.
When properly applied it will lay flat without waves or irregularities. Compression strength is comparable to plywood. Rhino-Hide can be sanded to a super smooth finish and painted with Supercoat Dope, epoxy paint or urethane. Not for use with water-base glue.
