Once applied, it dries into a tough, flexible black film that stays rubberized rather than brittle, so it can flex with the chassis instead of cracking.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eBuilt for the underside, not just the surface\u003c\/strong\u003e \u003cem\u003e(H2)\u003c\/em\u003e\u003cbr\u003eBeyond rust protection, the coating absorbs impacts from gravel and road debris, helping guard chassis and body panels from chipping.

Shake the can for about 3 minutes, spray from roughly 25–30 cm away, and build up the coating in thin layers — the manufacturer recommends 1 to 4 coats depending on the level of protection you want, with about 15 minutes between layers and a final dry time of approximately 2 hours at 20°C.
