Electronic rust prevention (ERP) units for cars have been around for many (15+) years now. Early on there was plenty of debate as to whether they worked in actually preventing or slowing rusting. Has anyone had experience with the latest versions? Do they work effectively or are they an expensive gimmick? Would be great for 2CV’s if they genuinely prevent rust but haven’t heard of owners using them.
Me thinks if they did work, every Northern European would have them. In lots of those countries cars don’t wear out, they just rust away.
Yes a waste of time. I restore 2cv for a living and seen almost everything under the sun in terms of rust prevention. I don’t like the word prevention, the rust will happen no matter what. The only effective way of slowing down rust is to oil wherever you can. Chassis rust from inside out, not the other way around. Water sitting underneath the floor mats is bad news especially rubber mats. Drill drain holes in the floors and fit carpets allowing evaporation. However trying to slow rust on a 20-30 old year 2cv is a lost case. Needs to be done from new. Join the club of millions replacing chassis and cut away rust (you’ll never talk alone)
good points … thanks John and CViking
