It is in a squeeze type tube and is copper/orange in color. It is a high temp, non-corrosive, fuel resistant gasket maker- ie.- you can use it on a real engine in place of a gasket.
Clean your engine well so it adheres good. Use liberally around the carb to ensure you do not block any passages.
Im not 100% but I believe copper version will destroy your engine. It has copper in it which creates a grit , the red doesnt. The red will also survive the same in a nitro engine. The copper is for higher heat ranges that nitro motors dont go.
