IN THE PROCESS OF TREATING A MEMBER WITH A COMPLETELY POLYMERIZABLE THERMOSETTABLE RESINOUS COMPOSITION, THE COMPOSITION BEING POLYMERIZABLE TO A GEL WHEN HEATED FOR 2 TO 5 MINUTES AT A PREDETERMINED TEMPERATURE, THE STEPS COMPRISING HEATING THE MEMBER TO A TEMPERATURE OF NOT SUBSTANTIALLY EXCEEDING THE ORDER OF 200* C. AND AT LEAST 20* C. ABOVE THE PREDETERMINED TEMPERATURE, DIPPING THE HEATED MEMBER IN THE COMPLETELY POLYMERIZABLE COMPOSITION FOR A PERIOD OF TIME OF THE ORDER OF SEVERAL MINUTES TO CAUSE THE COMPOSITION IN CONTACT WITH THE MEMBER TO POLYMERIZE AND GEL, THE THICKNESS OF THE GEL BEING PROPORTIONAL TO THE TIME OF IMMERSION IN, THE COMPOSITION, WITHDRAWING THE MEMBER WHEN A SUFFICIENTLY THICK THERMOSET COATING OF THE GEL HAS FORMED ON THE MEMBER, AND HEAT-TREATING THE MEMBER AND GEL COATING TO COMPLETE THE POLYMERIZATION OF THE APPLIED COMPOSITION.
