rust prevention
I have a 96 conversion van that I've been spending alot of time under with numerous problems. I'm surprised at the amount of rust under there. I haven't heard much about rust prevention lately.
Years ago...it was undercoating, then rust proofing. Last I heard was the best thing was nothing.
Very confusing to say the least.
The fuel lines, and all the brake lines have to be changed on mine. The frame looks pretty well affected too. Makes me wonder if this one is worth it or not. Looks like it might have been under water for a while. I'm not happy about this to say the least. I paid 20 grand for this van 6 months old, and 7,000 miles. I thought I'd still be driving this many years from now. Looks like someone was a lot smarter than me.
Anyway, next time I want to do what's best to prevent these serious rust problems. What are people using to stave off the rust that plauges the underside of these vans.
Any suggestions appreciated
Thanks

I don't know, but I'll be watching this along with you. The new "super-salts" the highway departments use now even corrode aluminum and copper more than NaCl alone did.
Is Ziebart still in existence?
I have an '89 and '95 E-250, and '97 Crown Vic and all have had all brakelines replaced.

FWIW: IT is hard to prevent rust because the basic design itself is decades old. When I lived in MA it was very popular amoung older mechanics to spray the underside of the vehicle with (used) oil and then drive it on a dusty or dirt road. Seemed to work on all their old rides.

rebecardo:
Whoa...you lost me there. Unless we used composite or specially formulated alloys, what does the basic design have to do with "rustability"? On the '97 Crn Vic, painted body panels look like new while right beside frame (though not as much), fuel tank, and brake line steel has rusted as though it were perfectly bare from day one.
Are you saying today's cars are designed somehow differently so as to resist rust in some new way? Today's body panels are lightyears ahead of those of the early seventies, I'll give you that.

rust prevention
I have used Eastwood's rust encapsulating paint, after preping properly.
It requires a topcoat. I am going to try rust bullet on my van's bottom and frame. You don't have to topcoat, and it requires less prep than either POR-15 or Eastwood. (I have heard good stuff about rust bullet.)
Thick undercoating seems to actually make things rust faster, from the inside out. I have been told this by a number of body shop guys who have seen the frames totally rusted. You can use thin undercoating that you can buy and use with a special undercoating gun (low pressure.)
Things still have to be prepped, though.
