Dynax S50 is the one with a \u003cstrong\u003e42-page independent report\u003c\/strong\u003e behind it, and it is publicly hosted.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eUniversity of Hertfordshire, School of Engineering \u0026amp; Technology\u003c\/strong\u003e (Report PG-BH13\/001, Dr Phil Green, 2013) ran a \u003cstrong\u003e2000-hour cyclic salt spray test\u003c\/strong\u003e based on ASTM B117-03 — 5% NaCl fog, cycled 10 minutes wet \/ 50 minutes dry at 35°C — with film thickness matched at roughly 50µm across every product tested. \u003cstrong\u003eDynax S50 ranked first\u003c\/strong\u003e, ahead of Mike Sanders Korrosionsschutzfett (which was applied at 500µm — ten times the film), Auson Noxudol 700, Rustbuster Mil-Spec, Dinitrol 3125HS and Waxoyl.\u003c\/p\u003e\u003cp\u003eThe honest caveat, which we'll give you rather than bury: \u003cstrong\u003ethe study was commissioned by Bilt Hamber.\u003c\/strong\u003e Independent laboratory, sponsored research. That's a meaningful distinction and you should weigh it. It's still vastly more evidence than any competitor in this category has put on the table.\u003c\/p\u003e\u003ch2\u003eWhat it does\u003c\/h2\u003e\u003cp\u003eS50 is a solvent-borne wax that \u003cstrong\u003ecreeps\u003c\/strong\u003e. It wicks into welded seams, lap joints and surface defects — the places corrosion actually starts — and leaves a \u003cstrong\u003esoft, brown, wax-like film that self-heals\u003c\/strong\u003e if it gets disrupted. That self-healing property is the entire reason it belongs in a cavity: a box section is a place you cannot inspect and cannot re-treat easily, so the film has to close itself back up when a stone or a bolt scrapes through it.\u003c\/p\u003e\u003cp\u003eBilt Hamber describe the corrosion inhibitors as \"highly polar\" and \"metal-seeking.\" They don't disclose the chemistry and neither will we — you'll find people online confidently naming the wax. They're guessing.\u003c\/p\u003e\u003ch2\u003eThe numbers\u003c\/h2\u003e\u003cp\u003eTarget film thickness around \u003cstrong\u003e50µm\u003c\/strong\u003e.

If the surface is wet, pre-treat with \u003cstrong\u003eFerrosol\u003c\/strong\u003e to displace the water first. Then the critical step almost everyone gets wrong: \u003cstrong\u003eleave the cavity open for 48 hours\u003c\/strong\u003e so the carrier solvent can escape before you refit the bungs. Seal it early and you trap solvent against the steel.\u003c\/p\u003e\u003cp\u003eCold product gets thick.
