I was disappointed when a link to that thread wasn't the first post

I am buying an 88 lx in a couple days and will probably have to drive it home. I live in NY and salt and snow is gonna get everywhere so what is the best way to protect it from rusting? Will 1 4 hour drive home cause any rust issues in the future?

If there’s no rust right now there’s probably no problem. If you’re worried take to a full service car wash on a dry day and get the underbody wash.

Rinsing will get most of the salt off but it will I doubt you can reach everywhere. Like above the fuel tank and behind the bumper covers.
Also oil or greasing can't reach everywhere. I do both but only to slow the rusting on daily drivers. On a true never winter driven car. It must NEVER be winter driven.

I am a big fan of RustCheck, but they are in Canada only (https://www.rustcheck.com/). However, another company is very similar called Krown (https://www.krown.com/en/) in the states. I've used both on my daily drivers, been very satisfied...

Ziebart coatings have worked on a bunch if my older cars. You set an appointment and they coat the inside of the panels and undercarriage of the car. My 84 had ziebart and never rusted except for a very small spot where the exhaust rubbed the rear frame rail. My 88 econoline has it too and has no rust under the van ( other than normal surface rust on bare frame ). No scaling and this has been my winter storm driver for about 5 years in maryland. The stuff works. The factory used to use it....if it has blue plastic plugs in the rockers it's been ziebarted.
