Hi,

 

My recently purchased 1992 300zx was imported into the UK about 3 years ago. Is it advisable to get it undercoated, and if so, are there different types and quality of undercoating ? I imagine the underneath must be pressure washed, is the coating they put back some kind of 'elastomeric bitumen' type of coating or what ?

 

How are zeds generally when it comes to resisting rust (I remember the 240z was a real 'rust bucket') I would have thought the zeds to be good on this matter, but there is a new post from a zed owner saying his zed is rusted beyond repair.

 

 

Thanks

 

John

I have never heard of a Rusty Zed and mine doesn't have a spot of it anywhere, even though it is 12 years old, with original paint !

 

Olly.

You'll usually find that UK cars are more prone to rusting due to 10 years or more of excessive salt on the roads (they use volcanic ash instead of salt in Japan). Most Jap spec Zs are undersealed just as well as the UK ones, but it can't hurt to give them some extra protection.

 

For full protection you need to get the waxoyl etc inside the panels too, as they can rust from the inside out due to water seepage. If you take enough trim off you'll find some holes you can use for access; better than drilling new ones like some underseal places do !

 

Best to get the car steam cleaned underneath first then let it stand for a day or two to dry.

 

The Z club magazine does advertise some device that electronically prevents rust but I don't know anyone that's tried one

 

You could always go the whole hog like I did and dry line and insulate the garage then put in a heater and a dehumidifier. You know it makes sense ;)
