I have a 1990 240SX hatchback... it has minimal rust, but it does have the typical rust problems of our beloved cars... [IE; front strut towers, area near front subrframe...

But my rust is easily repairable ...

However, My car was driven by someone who lived or drove on a dirt road almost everyday... so the underside of my car is covered in caked on decade old dirt. What is the best way to clean it like new?

I was thinking maybe I could put it on a lift, and powerwash the under side of the car, then just drive it a bit and let it dry?

when i repaint my chassis do i need to have the underside sandblasted and painted too?


didnt see a thread for this, so thanks for any help!

 

Lift and pressure washer will do, slowly, but it will do.

As for repaint, the under body has a material similar to bed lining (for the most part) But its up to you on what you want to do after you clean it.

 

+1 For the bed lining spray. You can actually buy it in cans and spray it, I have some I will check on the name of it and will post it for you. For the underbody a pressure washer will do or you can use mean green and some elbow grease, but if you have access to a pressure washer it would be faster

 

Any bed liner material will work, just pick up a gallon or so.

Make sure you go over the underbody with 60 grit sandpaper before you apply.

 

UHHMM hm

just make sure you clean it very well.. dont bed line dirt hahahahah.


go get r done bro. pics of before and after for us.
