This 12 oz. aerosol from Design Engineering penetrates and bonds to heat wraps and compatible metal parts to create a durable, protective barrier. The formula is engineered to reduce contamination, delay degradation, and improve the usable life of heat-management systems without altering fit or flexibility.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this spray improve the lifespan of exhaust wraps?\u003c\/h3\u003e\n\u003cp\u003eThe silicone-based coating seals fibers and blocks contaminants that accelerate wear—such as oil, grime, and moisture—so wraps retain their insulating properties longer. It also resists cracking and peeling under thermal stress, preserving the wrap’s integrity through repeated heating cycles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePenetrates and bonds to wrap fibers to reduce fraying and breakdown\u003c\/li\u003e\n  \u003cli\u003eCreates a dirt- and oil-repellent surface for easier cleaning\u003c\/li\u003e\n  \u003cli\u003eReduces abrasion from contact with other components\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat temperatures and curing steps are required for reliable performance?\u003c\/h3\u003e\n\u003cp\u003eThe product is formulated to withstand extreme temperatures up to 1200°F once fully cured.
