late not on Electrolytic Derusting,,, just go into it and yea it takes a big vat to derust and entire chassis or the entire vehicle ,, but IT works. Built me a vat large enough to put an entire truck in at one time and use several 40 amp battery charges on stainless stell sheets on all 4 sides,,,,takes a while but it sure works well and it is Cheep!!!!!! Need less to say it is very easy also. On on occasion maybe not but for several it is very practical .
