Chlorine-free and easy to apply, it significantly extends the life of coatings, proven by rigorous TÜV testing and industry accolades. Ideal for professionals seeking reliable, long-term protection for steel surfaces in automotive, marine, and restoration projects. ## Description Traditional paints and coatings applied to corrosion give disappointingly short-lived performance because they simply hide the underlying and continuing corrosion – the failure is first seen by blistering of the coating and the rapid breakthrough of rust. Hydrate-80 provides powerful protection to rusted steel surfaces, its electrochemical function stabilises existing corrosion by converting the iron oxides into a protective metal complex and it also combines with surface moisture and oxygen depriving the corrosion process of the conditions it requires. Paints and coatings applied to a Hydrate-80 treated surface demonstrate amazing improvements in long-term performance. Hydrate-80 provides a superior stable barrier to prevent further attack. The cross-linking polymer formulated to provide the tough non-rubbery barrier tenaciously grips the metal surface forming an ideal base for further coatings, paints or anticorrosion wax. Importantly for long-term protection Hydrate-80 doesn’t contain chlorine which is known to transform into corrosive hydrochloric acid in rust converter applications causing under-film blistering and destruction of paint finishes or other coating products. Long-Term Performance The long-term performance of Hydrate-80 has been proven to significantly increase coating life in independent tests conducted by the German TÜV organisation under conditions of VDA 621-415 (6 cycles, or 1008 hrs) which included exposure to hot salt-spray, 100% relative humidity and drying atmospheres with each cycle lasting 168 hours. Hydrate-80 was awarded Practical Classics magazine “Best Buy” and “Product Recommended” after a long-term trial comparing it to 12 other products – in fact Hydrate-80 was applied to more heavily corroded steel than the competition and still outperformed them. Hydrate-80 has been used to arrest and prevent corrosion in diverse applications – from massive marine installations to classic and historic vehicle restoration Hydrate-80 provides dependable long-term protection. Review: Vastly superior to any Hammerite, Jenolite products - This is the best rust convertor in my opinion. Forget about Hammerites Kurust and Jenolite rust convertor etc they aren't designed for the underside of a vehicle. I know I've used them. If you are going to go to the effort of getting under your car and spending time (hrs in my case) wire brushing flaky scaled corrosion on sub frames and wheel arches then for godsakes buy a quality product. Bilt Hamber Hydrate 80 is the way to go. It is formulated specifically for the underside of vehicles and boats, yes boats so you can imagine this product has to be good and it is. I used it on my 20 year old Corolla, two coats (let dry 24hrs) before applying Bilt Hamber UB wax again two coats. I know this protection will last a few years easily, unlike Hammerite underseal/waxoyl which lasted 6 months I found. I really don't want to be under my car again anytime soon it is a labour intensive uncomfortable job treating corrosion. Review: I am satisfied with this product - It does convert rust to something else ## Features - Stops corrosion process, Prevents paint blisters later on, Amazing long-term performance - Neutralises forming a stable solid mass - Doesn’t contain chlorine, Surfaces do not need washing after treatment - Easy-to-use: simply brush or spray apply, Produces super-tough non-rubbery etched barrier - Safe, water-based and non-flammable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00672US20 | | Best Sellers Rank | #3,121,331 in Automotive ( See Top 100 in Automotive ) #1,546 in Care Corrosion & Rust Inhibitors #19,727 in Oils & Fluids | | Brand | Bilt Hamber | | Customer Reviews | 4.7 4.7 out of 5 stars (345) | | Date First Available | February 19, 2015 | | Item Weight | 1.52 pounds | | Item model number | 217 | | Manufacturer | Bilt Hamber | | Manufacturer Part Number | 217 | | Model | Hydrate 80 (500ml) | | Package Dimensions | 10.43 x 2.91 x 2.83 inches | ## Images ![Bilt Hamber Hydrate 80 (500ml) - Image 1](https://m.media-amazon.com/images/I/51PKjJr-mjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Vastly superior to any Hammerite, Jenolite products *by A***R on September 8, 2026* This is the best rust convertor in my opinion.
