Bilt HamberHydrate 80 Rust Killer – 1 Liter

Excellent product, easy to apply and does what it says, it halts rust in its tracks.

As it says above

Arrived next day so i got straight to work on my trailer, bilt hamber hyd 80 is top tier. Covered both sides, then went over patches that i felt were lean, after several days i put down a top coat. Job done.

Quick delivery and product seems to apply well and do it’s job…but is costly… so can’t do large area without being expensive

Heavy rust on sills, used an angle grinder to take off the worst, painted with this stuff which goes on almost like milk (!) before it reacts with the rust and turns black. One month later and no rust has returned - and this is in winter!I painted some remaining fluid onto a cast iron vice that is permanently outdoors. no preparation but it still shows no signs of rust on the treated area.Excellent!
