Easy to use, dries quick.
Bought x4 tins of this to do the underside of my full fat range rover. Got all the rust off with wire brush and sandpaper, then used Bilt Hamber Hydrate 80 to convert the rust spots to a stable base (nice colour change to show where you've been as showing in the pic). Just put a decent coat on the front half of the car (subframe, panels, suspension droplinks etc, the bits that were rusty and everything else ((not brakes or exhaust)) and it goes on very easily. Even with using too much it dried before it dripped down on my head. I'd painted the exposed metal elements with Hammerite Direct to Rust paint a few days ago which was blue, a little sad this has been covered up by the brown wax but at least I can easily see where I've sprayed. All in all, very impressed with the product. Will use the other tins for the rear and probably my other cars too as I've got 3 full tins left :D

Perfect as always
This company does not need a review on any of their products, they just work very well and very cost effective. There is enough in this can to do 2 family cars and because it’s Bilt Hamber I know it will last! Used in conjunction with Deox-gel… perfect combination

As easy to apply as deodorant
This stuff came recommended by a friend at work who works on cars allot and is a professional sprayer and detailer. It didn’t disappoint. Easy to apply once the prep was done. I scraped off loose rust and then wire wire brushed with a wheel attachment on my drill. It comes out in a fine mist rather than a viscous sticky substance which is what I feared products like wax oyl would do. Time will tell how well it lasts but if it last 2 years without showing any rust I will upgrade this review to 5 stars. I recommend

Beats Lanogard and Fluid Film every time!
Ok here is eight years in my van and still going strong with no reapplications! Forget linseed oil Lanoguard and Fluid Film! They smell and dry to a sticky coating that attracts dust and debris! Go with Bilt Hamber and never regret it!

Very good product on rust
Very runny compared with the normal Dynax wax. Needed to collect the drips off the car in little foil trays dotted around the ground. Used on LandRover chassis and underbody. Goes on well and sprays fine. No idea if it will last but no rust poking through yet. BH waxes seem to be in a league of their own.

Good product 👌
I have been using this for a couple of years and my 1967 DS has no rust. Can't say more than that.
