Think I’m going to skip the ACF 50 and jump feet first into their Corrosion Block !

This stuff looks like a more heavy duty application and something that has the ability to cure rust and stop the advancing rot ? I’ll apply it under the wheel arches once I’ve removed the wheels and the arch liners, also coat the suspension uprights and springs and get up into the top mounts.

Still not sure if ACF 50 is best for the suspension as the block might be too thick ?

As for the atom Mac, I’m not sure applying this when the disks are new will keep them looking that way, it doesn’t last and on the brakes with the heat generated it will probably be all off in an hour ? The application of this stuff is for appearance more than anything, sure it will help relieve corrosion on garden spades or even on bike frames but the brake application is mostly used for stopping the callipers binding on after washing and then putting the car away wet and rust forming, it’s the braking then that removes this rusty residue and the flakes when red hot hit the wheels and penetrate the lacquer which then let’s salt in helping corrosion to get under the surface and start to blemish the wheels, apply when wet thro straight after hosing and it will help coat the surface resisting the air turning the disk rusty. I don’t think as above it’ll do much for the inside edge or between the venting inside the disk ?

To be fair the undertrays do a very good job of keeping most dirt and crud away from the floor and pipework, I removed mine to inspect everything, all good so a thorough hands on clean then soaked everything with ACF50 and let it drip for a day or two.

The most important things to do are regular arch liner removal to remove anything thats collected there but also the jacking points, these hold crap and need cleaning out and coating in ACF50, if the sealer has peeled off them due to unprotected jacking its good practice to “touch in” with brushable sealer.

Just to add the image above is dripping with freshly applied ACF50, it does dry off to a nice clear finish, the garage took quite a while to lose the odour....
