The construction of large, seamless components is a main application of modeling pastes. The pastes usually get applied mechanically on undersized substructures. Then they get re-milled to the proper dimensions.
The surfaces are characterized by a good pressure resistance, seamless appearance and partly by a high temperature resistance. Pastes can be varnished well and enable the production of big high-gloss varnished components on which no adhesive points will be seen later on.
