These covers are manufactured from high quality engineering plastics, primarily PETG.

PETG was selected after testing due to its strong layer adhesion, chemical resistance, and dimensional stability. It performs reliably during vapor blasting, media blasting, surface preparation, and masking for coating processes.

The material offers:

● Excellent impact resistance
● Good temperature tolerance for coating preparation
● Resistance to moisture and common workshop chemicals
● Durable thread engagement for repeated installation and removal

Each component has been test fitted and evaluated during real engine preparation procedures to ensure dependable performance in workshop environments.
