The Monster Under Our Bed, RUST: What would you do?

[kfitz77555]

So I recently just ripped out my carpet to wash it , because let me tell you, that stuff was dusty.

While doing this I was rather surprised in the over all condition of the floor. Except the driver's side....

I knew I had a rust issue on the driver's side. Back in December I fiberglassed the drain hole because the plug was missing and it was starting to let water in...ouch I know.

So here I am now looking at an even larger rust problem.
What advise to y'all have for me?
Is this save able?

Thank you in advance.

Clean off the rust, make the repairs you need to make.

Once you do that and the rust is gone, get a a twice a year plan of spraying Fluid Film on the chassis, underbody, inside of the wheel wells (by removing the inside plastic side panels and the front plastic fender wells.

Finally, get the necessary attachment that has a 360 degree nozzle on a long thin tube and slowly pull it through the frame by the frame holes while spraying.

Do this twice a year and rust will never progress, I mean ever in the spots you have sprayed.

You can throw a coat of paint on your repairs or leave it bare, doesnt matter (this doeant apply to the inside of your floor pans of cojrse) Everything needs to be coated in Fluid Film. Its an enviornmentally safe product, tacky, with no smell. Best stuff in the world.

There is a kit that comes with air tools, but I use an electric paint gun, a gallon of fluid film and then a few aerosol cans with the 360 degree snake attachment for inside the frame. About a 100 dollar investment.

Ill throw up a few pictures.

The only way to completely stop rust is to cut it out and replace. Not sure if these trucks are old enough for someone to make quality replacement parts. You might have to fab up your own. There are plenty of good videos on youtube about forming and shaping patch panels.

I might have to look into this Fluid Film. With my recent move out of So Cal to the snow country, one of my biggest fears are my rust free trucks rotting away from the winters!

This is how it looks on the vehicle, and this is basically how it stays. Does not swell or damage rubber, does not come off in rain. Oily metal cannot rust. Humidity and water cannot penetrate it. Several road saltings will begin to strip it, but if you spray just before winter you can make it through without damage, thrn just reapply after winter. the most important part is inside the frame.

Oil coating is popular in Canada, a little more rare in the states. Some shops offer this service but it is a 30 minute job with an electric paint gun, as it sprayd so wide.

I would fix it OP. My rust is all over the frame and all in the quarters. I have a wrecked 86 with a perfect body from the windshield back that im going to have to put my front clip on and do a SAS just to make one nice runner. You got a lot less work ahead of you just fixing what you got.

Its not that bad based on the pictures so the sooner you fix it and fluid film it the sooner you stop the rust.

Sorry about pic, I need a new site to host pictures but have no clue what to use.

 

[kfitz77555]

So plan as of now.
Try and stop the rust and keep it from getting worst.
More fiberglass for the holes? Bad idea good idea?

Second phase
Look for another to replace this truck.(which I really don't want to do)
Or save enough money to take this thing and do a frame off service on her. I have looked on line but it doesn't seem like there are any after market floor panels for these trucks. I believe I'll need someone to cut of the entire drives side floor panel and we'll in some new steel.
Which sound like $$$

Here are the photos. This is a twenty nine year old chassis and body that has been driven every winter in the northeast.
In comparison, my father had an 86 Toyota 4x4 pickup he bought new, and it was scrapped in 1995 from frame rot and bed rust.
No Fluid film where I live: 9 years to scrap.

That is how you apply this stuff, but this video is done with a guy who uses motor oil, which is also super effective...but less ideal.
