On a chassis or inside a box section, nobody cares. On a painted underside, a restored bay, a visible subframe or a show car, that brown film is the problem — you've protected the metal and ruined the look.\u003c\/p\u003e\u003cp\u003eDynax UC is Bilt Hamber's answer: a \u003cstrong\u003efirm, touch-dry, virtually transparent\u003c\/strong\u003e protective film at around \u003cstrong\u003e50µm\u003c\/strong\u003e. It goes on bare metal or over paint, it's safe on the majority of paint coatings, and it leaves the finish visible.\u003c\/p\u003e\u003ch2\u003eMulti-metal inhibitors\u003c\/h2\u003e\u003cp\u003eBilt Hamber describe UC's film as rich in \u003cstrong\u003emulti-metal corrosion inhibitors\u003c\/strong\u003e — a deliberate distinction from S50 and UB, which are aimed squarely at ferrous metal. If you're protecting aluminium subframes, mixed-metal assemblies or galvanic junctions, that's the reason to reach for UC.\u003c\/p\u003e\u003cp\u003eAs with the rest of the Dynax range, the wax and the inhibitor chemistry are undisclosed. Bilt Hamber name the carrier solvents in the SDS and nothing more, and we're not going to fill the gap with speculation.\u003c\/p\u003e\u003ch2\u003eWhere it belongs\u003c\/h2\u003e\u003cp\u003ePainted or visible undersides. Restored engine bays. Inner arches on a car you actually look at. Anywhere a dark underseal or a brown cavity wax would detract from a finish you've paid for.\u003c\/p\u003e\u003ch2\u003eHow to use it\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDegrease with Surfex-HD\u003c\/strong\u003e, rinse, dry thoroughly, then wipe down with white spirit. Apply in \u003cstrong\u003efine coats\u003c\/strong\u003e — this is a low-build product and it is not trying to be UB. The aerosol valve works upside down, which matters more than you'd think when you're under a car.\u003c\/p\u003e\u003cp\u003eIt's removable later with solvent or an alkaline degreaser, which makes it a sane choice for anything you might need to work on again.\u003c\/p\u003e\u003ch2\u003eUB or UC?\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eUB\u003c\/strong\u003e where it takes stone strike and abrasion, and where nobody sees it — outer chassis, floorpans, wheel arches. \u003cstrong\u003eUC\u003c\/strong\u003e where appearance matters or where you're protecting mixed metals.
