Hi

I´ve a question concerning the rust protection coating on the underside of the car. After 14 years respectively 14 very hard winters the black stuff needs to be renewed. Of course I refreshed it every two years but on some places it ist getting more and more cracked up and will soon not be able to protect the underside of the car from rust. So I´ve decided that it has to be removed completely also to gain access to metal plates from the outside. From the inside, when you lift the carpets, the floor plates look like in 1989 - no bullshit it´s perfectly true I swear!!!! I never had problems with water resting on the floor or stuff like this! Nevertheless there are some rust pickles visible from the outside on the black stuff underneath the car - they must come from somewhere so the black stuff has to go.

Now my question: What is the best way to remove all the black protective coating, what tools will be needed for that type of work and finally what is the best way to make it rustproof for long time - and lots of hard winters - again?

Thanks for any advice :-)

Ciao
