Bilt Hamber Atom Mac Migratory Contact Corrosion Inhibitor BH-AM300ML B20C

Easy to dilute to instruction, stops discs turning orange after a wash so keeping alloys clean from spray. Top quality, nice packaging.

So my intention with this was to spray onto brake discs after an initial rinse to stop them from rusting during a wash.That totally didn't work, the iron remover goes straight through and rusts the discs.I love every other Bilt Hamber product I have used, so I really wanted this to work. I have washed about five cars using this now, upping the concentration and frequency of application each time, to the point where I reapplied it every time the discs got wet. There is a very slight improvement, but nothing worth the trouble or the shelf space this takes up.I was going to use up what I have and not buy it again, but now I'm thinking of just getting rid of it. Pointless stuff, I don't know how this is getting such good reviews everywhere.Bilt Hamber is a fantastic company, but Atom Mac is a real miss for them, disappointing.
