Surface rust.

Hi Folks, 

I bough a stunning IS 250 Convertible from Lexus, it’s been lovingly looked after, full service history great MOT history, paint work stunning, but on having the diff oil changed the mechanic pointed out surface rust under the car, he was not worried but I want perfection, he recommended Dynax and said he would Wire brush the rust off and apply 2 coats of this product, talking to the garage they said it’s a failure on many Japanese cars, I own a SL300 Mercedes classic 1992 with no under car rust whatsoever! Anyone have the same problem?

Hi Gary,

Been there, done that.

On mine it was primarily confined to the extra crossmembers at the rear that are fitted to the ISC to add extra rigidity. I removed these, removed the surface rust and refinished them with multiple coats of zinc primer, black underbody paint and clear lacquer. The rust was more unsightly than structural. It can also affect the plates from which the rubber fixings for the two rearmost exhaust boxes hang.

So far I have not found anything that causes me any serious concern rustwise.
