Need Rust Prevention Ideas

[UGLY OLDS]

My brother had one of those electronic rust preventative gizmos on his bought new '89 T-Bird.. Doors, fenders & quarters rotted through before the payment book ended..

I worked for a company that completed the up-fit on Bell System trucks & prepared them for service .. We rust-proofed these vehicles with a wax/cosmoline type of material that stuck to everything & never dried .. Rather than drilling holes, we removed panels to assure proper coverage inside doors /quarters/etc .. Three years later..Rotted through panels ..

When we scrapped my '89 GMC pick-up with 110K miles, I had guys fighting over the rust-free front clip..( I flushed all the "hidden" areas with water every time it was washed ). The sad part was bolts we had to torch off because the heads had rusted into little round "nubs" , OR..  The exhaust manifold that I had to replace because the part of the manifold that one of the three exhaust pipe studs threads into rotted off ....( The cast iron ...NOT the stud ..) ..

The photo below shows what was left of part of the frame rail .... :evil:

 I really don't thing that there is a resolution for vehicles in our part of the country...

As long as we are on this subject, I have a couple more stories for you.  Years ago when Zeibart was all the rage, I worked part time in a body shop.  The discussion on rust and rust  proofing came up.  There was a 66 chevy hood that the back side was sort of rusty  and we coated 1/3 with new motor oil, 1/3 with used motor oil and 1/3 with I think was Quaker state rustproofing-  looked like beeswax.  The hood was thrown out back and forgotten about-  went thru summer, fall, winter and in the spring when they were cleaning up all the old sheet metal, the hood was rediscovered.  The new motor oil side was washed off and rust  was showing.  The Quaker state piece had washed away and was rusting.  The used motor oil piece looked like the rust had been converted to black iron.
 Also years ago when I was in the AF, a Tsgt I knew used to change his own oil and He took the used oil and put in a squirt oil gun and put the nozzle between the glass and weatherstrip on the doors and squirted oil in there.  Squirted oil in the front fenders and poured the rest in the 1/4 panels via the trunk.  The car was coated with sticky dust on the bottom, but not a speck of rust...  Tom...

I have found that people who go on about their great rustproofing..rust free...this that..at the end of their story..they do not drive in  winter,salt,keep their cars in dry heated(always about the same temperature garages)OR they did and they dealt with the rust as best they could and don't do it anymore.
 Paint as idj says..then something that will creep.
  There are just too many components and now made crappy..that cannot be rustproofed,protected. Wheel bearings,rotors,calipers,hubs,axle shafts,stainless exhausts over about 12 years. Brake pads that after enough time seem to just rot right off the shoes..not uncommon.
  I had 2 identical vehicles..1 rustproofed regularly..it rotted right at the frame dog leg where they drilled and plugged it..
  The other one rusted and the same spot

   A car I am driving right now was sometimes rustproofed twice a year..I hate to admit it :oops: Recently I found ROT in one of the back lower quarters..it had gotten UNDER the paint was going at it from the OUTSIDE :cry: You would never know it unless you felt it with your hand..can't see it right now unless you get under it and feel it.

Two stories.

One, a body shop owner I know, uses used motor oil on his pickup. He has done this on his last four pickups, keeps them about 10 years, and sells them. He does it twice a year, fall and spring. It drips for a few days, but soon stops, and they always look good.

The other one was an old farmer that sprayed his 49 Chevy pickup with Kerosene every few months. He drove that pickup over 50 years, and it still looked like new

I like Tectyl undercoating, on my GMC I used that when I built it, as I assembled it, and it held up for nearly 20 years.

I read somewhere that they use the fluid film spray for rust coating . That stuff sure clings to stuff . I am just about to start cleaning off the underside of the T coupe and plan to POR 15 it on all surfaces of the inner structure that holds the body together . I am also considering riveting the floor to that same frame so that the coating is not burned off by welding in the floor panels . I will likely por 15 the entire inside of the body as well . I will try to dribble the stuff in between the seams of the body too . Obviously this will not be driven in winter but I want to ensure that it does not rust again . I am fortunate that this vehicle has been in a barn or my garage for the last 30 years and the body was still on wheels when I got it so never sat in the dirt .The car was repainted once and still has half or more of the body still painted .
