Hi, Last week we did an Exeter and return journey and the roads were filthy especially the A30. When we arrived back home the Alphard was covered in mud and road salt and as it's white it looked awful. The next day it was out with the pressuere washer and a good wash all over plus the wheels, wheel arches and anywhere there was salt. This was followed by a wax and wash. The point of relating the above is just to remind you all to make sure you clean out the lip on the edge of the rear wheel arches.Once we get a dry period, I intend to make sure I have cleaned these areas and once dry smear some grease. The front arches are OK as there is an inner wing lining.

If you look at some of the earlier Mazda Bongos,many have corroded rear wheel arches and although the constrution is different it is a good simple remedy to prevent corrosion.

 

Hi,I would spray acf50 in any hard to reach areas it will stop rust starting and stop any already there. It's not cheap but does work. 

Thanks for that,will try some although it has to be sprayed each year according to the advice.

I use my air compressor with a suitable air jet gun to blow what water has congregated in the gaps😎

Yes acf50 will wash off but it's so easy to use no mess at all, it's no real pain other then the cost lol it's something I've used on my motorcycles for the last 15yrs so know it works well
