and im currently doing a rear beam and trailing arms.
Ill post some pictures on here when im done. Its VERY effective and will remove all traces of rust and will leave
a lovely black finish that you can prime when dry. Easy peasy minimum effort required to clean up after and
best of all its virtually cost free except for electricity. The only down sides are it can be very messy and it can
take upto a couple of days to clean off serious corrosion like you get on brake parts etc.
IMPORTANT POINT!!!
DO NOT TRY THIS IN YOUR HOUSE. The gas that is given off is hydrogen which is highly explosive.
Outside is preferable but you can do it in the shed/garage as long as theres good ventilation.
