I'm restoring my '66 GTO. I want to rustproof the inside of the doors and the trunk quarters. What is the best product to use?

[6704gto]

ive heard of sqiurting oil on the inside of the quarters and doors

[GT182]

Gibbs Brand found at www.gibbsbrand.com. And yes it does work as advertised, I have proof on a brake caliper that shows it works.

well as you guys probably know fish oil is great....really its still the best, a friend of mine who has all the tricks said buy the fish oil in a tin not spray as its too thin, just buy tins of it and brush it on, i stripped my interior and did 3 coats, it took about 2 weeks to do as each coat needs about 4 or 5 days to dry up a bit, my friend painted a bare metal piece about 20 years ago and its been hanging in his shed ever since and still like new, the other tip is the factory put a coating inside the doors but it stops about 5 inchs down from the top of the doors inside, these doors condensate as they are pretty much sealed up and over time that inside shoulder on doors and just under the rear roof piller gaurd start to rust, i bet if gto owners took off door trims and stuck there arm up inside door and felt under that shoulder many will find rust....this area would easily go unnoticed...check em guys !

Is there any fish smell?

[fiesta62]

no smell , you can buy deoderised fish oil so it dont smell, i bought a brand called white knight but there would be lots of different fish oils available, it gets messy i had it dripping out of all the cracks and holes into trays and it dripped for a few weeks after i finished, but no big deal, its all done now and you wouldnt know, no after smells, i did brush on most of it but i did also use a few spray cans with that thin tube nozzel to get at the really hard to get to spots, i also used a small mirror and a light to see up those spots inside doors and high up in the rear gaurds , my car will never rust i made of that....

The auto body repair insustry uses a wax that sprays into hard to reach areas, like frame rails that are boxed, and sectioned A pillars, etc. Kind of like the cosmoline used on guns by the military. Never stops protecting until you scrub it off with gasoline or solvent....and even then, it's a real mother to get off.

Where would you get that?

Sounds like LPS 3. Used in the lower belly of aircraft cargo holds to prevent corrosion. Dries to a waxy film layer.

Amazon has 1 gallon jugs for around $65.
I've been thinking about using this to rustproof the rocker cavity on my 66. Tape off all the drain holes, fill with LPS3, then drain into a pan to reuse for the other side.

[geeteeohguy]

We actually use LPS-3 on our milling machine and lathe at work, as well as other equipment we don't want rusting. I don't know if the autobody wax is the same, but the LPS-3 would certainly do the job....basically it's spray cosmoline....tough stuff.

I havn't used these products,but would like to know myself if any of these are worth using.

i'm not sure about any other products but the thing is with a lot of products they eventually dry up, then go hard, like bitumen based rust products, bitumen is good but it eventually drys up and cracks, if any air gets to the metal thru any crack then its all over the rust will start, fish oil never goes hard or brittle it never cracks it will always seal up the area, also it will run into the tinyest little hole or crevice it gets everywhere, i'm not sure if other products would be as penetrating as fish oil, there might be better products, but we all know fish oil is proven , yes its messy but now its done i can see there is no chance of any rust starting now

I've used this stuff by Crest really gets in between panels and comes with a long 30in extension for hard to reach area's. Tom http://www.crestauto.com/products/coatings.htm The Honey Coat stuff.

[Cardo]

This looks to be the same type of product as the Honey Coat at about half the price. I just ordered it, we'll see how it works. https://knasupply.com/ies-inter-guar...s-4557-ies4557

My process of rustproofing the inside of the doors is:

1) Scrape off all the factory sound-deadening "tar"
2) Use a wire wheel to bring everything down to bare metal (as much as you can reach using various tools)
3) Apply a direct-to-metal rust inhibitor
4) Apply an epoxy primer/sealer
5) Install Dynamat where applicable
6) Spray inside with cavity wax

FWIW, fish oil is what Rustoleum uses in their paint as an additive. As has already been said on fishing boats it was noticed that anything that got fish oil on it even in a salt water environment would never rust. So there is truth to what was posted about fish oil retarding rust. Commercial bridge paints also use fish oil because of the road salt the iron is exposed to every winter.

I assume this is why Rustoleum remains fairly pliable even after it dries it never get truly hard.

A newer spray I have heard a lot about is Fluid Film, last year I talked to a friend of mine in Erie PA, my former home town that owns his own garage. He told me most everyone in Erie has been using it in the fall to undercoat their vehicles, seems it has done very good for the users. I guess it's available in gallons that you can spray on with an undercoating type sprayer. Amazon sells it for $38.35 a gallon, $160.99 for 5 gallons: https://www.amazon.com/Fluid-Film-Pr.../dp/B004NDDCKK

The major component is wool wax. I've used the spray cans and it does work on rusty stuff to free it up and keep it from rusting after going back into service.
