Chevy G20 van needs undercarriage love and care Sign In

Hey guys, first time user to the board - hope all is well.

First and foremost, I'm not a big car guy (though I find working on them fun as hell, just never had many venues or reasons to learn) so I don't know a lot. I inherited a (in my opinion) really awesome gigantic Chevy g20 high-top van. It needs a lot of love but it's operable. I have a specific question about "refurbishing" a certain part of the van...

The entire undercarriage is rusted. Not like I-can-poke-a-hole-through-it-with-a-pen rusted, but it's mildly bad. I have personally used WD-40 to get rid of rust WONDERFULLY on many metal parts before, but seeing as I don't know how cars work entirely, but I DO know WD-40 is flammable, I don't want to spray parts that get hot.

On the other hand, I know WD-40 was created to protect missile parts and this, from the wiki, could be potentially beneficial as once I get rid of all the rust with it, it can remove itself from heat and make way for me to regrease. I just don't know however:

>"Using penetrating fluids as general-purpose lubricants is not advisable, because such oils are relatively volatile. As a result, much of the penetrating oil will evaporate in a short amount of time, leaving little residual lubricant."

What can I use to remove all the rust from under the vehicle, and when can I use to regrease everything? I don't even know what parts need to be greased honestly, but it all needs some shine. Thanks so much, looking forward to your answers.

You're giving WD-40 way too much credit. It isn't going to remove your rust. About the only thing that will is a sand blaster and many hours of work and even then, it will come back eventually.

You'd need a frame-off restoration to get rid of that rust. You can drive it so long as the frame rust isn't enough to compromise the structural integrity of the frame. For the price of fixing that rust you could go buy another van from a state that doesn't use rust and still have money to spare.
