EW Interior rust spray

EASTWOOD'S INTERNAL FRAME COATING
 
 Many times during a restoration, I've run into situations whereby while I know there are are methods that can negate rust in various ways, there's always this one area that has eluded restorers best efforts. These areas are the ones that are inside enclosed areas: frame rails, windsheild pillars, cross members and the like.
 
 Rust-abatement takes on many forms. From sandblasting, grinding and filling to phosphoric acid solutions, rust paints and primers, the to tried and true method of cutting and replacing bits of metal here or entire panels there.
 
 How to tell?
 
Often, there are tell-tale signs that an area is rusting  from the inside: it shows through as a bubble, several bubbles or perforations. More often than not however, there is no outer signs of rust forming below - until it's too late that is.
 
Rust can be extremely close to perforating a surface yet completely missed - even in a top quality restoration. Imagine delivering a $60,000.00 frame-up restoration to a paying customer and a month later rust bubbles are forming on the rocker panel! Now imagine that project is your own. You've spent 1000's of hours on it over several years only to see a flaw - like the proverbial wart on a nose -  growing before your eyes on your perfect ride. If there was something - anything - that could be done to thwart such instances, you can bet you'd want to use it - right?
 
Enter Eastwood Company's Internal Frame Coating spray, with it's specially designed conical nozzle at the end of an 18inch tube applicator. This system was designed to get the product down deep into frames and other enclosed areas, to coat the inside surface against further rust damage. I know for a fact it could have helped on several past projects that continued to rust from the inside out. On one vehicle in particular -  my prized 1967 Ford Galaxie 500XL Convertible - the frame continued to rust from the inside until it perforated the thick frame rails.
 
 Not Just For Frames
 
One of my current projects, a 1956 Chevrolet 1300 1/2 ton truck, has a few areas that fit this description and are perfect candidates for Eastwoods Internal Frame Coating spray. While the majority of the frame on these trucks are of an open design, the cross member is enclosed and will easily benefit from the application of this product. While Eastwood markets their spray specifically for frames, I find there are many more areas and applications it can and should be used. As important (and perhaps moreso) are areas of the body that are enclosed, but at the same time exposed to rusts' perfect conditions, such as enclosed box corners and the windsheild pillars.
 
Eastwoods Internal Frame Coating is formulated to both convert and encapsulate rust. It  incorporates an oily film, as well as zinc phosphate to further protect metal from future corrosion. The viscosity is somehwere between WD40 and 30wt oil, meaning that while it sticks to the area sprayed onto, it also moves and flows enough to penetrate into seams and pinch welds. As per Eastwood, it penetrates into the existing corrosion, arresting it where it starts.
 
 Of course another rust spray wouldn't be much of  story without some way to get it into those areas being discussed.
That's where Eastwoods special nozzle-applicator shines This so-called "conical" nozzle sprays the product in a 360 degree pattern and resides at the end of an 18 inch tube, long enough to reach into hidden areas to spray the product onto all sides within an enclosed area.
 
 
Application
 
At right is a view into the enclosed end of the box side of this 1956 Chevy Truck. The rust is easily evident and will surely continue unabated, unless something is done.  Trying to apply a rusy product deep into this area is difficult at best and likely most of it will end up with little or no rust protection.
 
 
 
 
With the conical applicator nozzle I sprayed Eastwoods Internal Frame Coating into the enclosed area. It went on evenly, coating it in a 360 degree fashion. I could also see that there was enough material emitted - of a sufficient viscocity - that is would both coat all sides within the box-end and enter the gaps where moisture and debri would otherwise sit and continue the rusting process.
 
 
 
 
 
 Windshield Pillars
 
Until recently, unless you where somehow able to apply a rust paint with a long brush or applicator - which doesn't work well in many circumstances - there was little you could do to give these areas a measure of protection.  At right is the windsheild pillar on this 1956 Chevy Truck which, although I did brush on a well-known rust paint to the areas accesible when cut for welding, there where still large areas above and below the repair area with no protection from further rust formation.
 
 
 
Again, inserting the conical nozzle as far up into and around the windsheild and roof pillars as I could, I was able to spray a good amount of the product into all areas. Certainly this would be better than leaving it as it was, exposed to the elements and a trap for moisture. The Eastwood coating will definitely keep that moistue - and therefore further rust - at bay.
 
While long-term testing will be required to see how good the rust protection will be, there is little doubt as to the benefit of using this product, with it's unique applicator and proprietary blend of chemicals. Certainly the benefits of an oily film - to ward off moisture, as well as Zinc - to bind rust, have been known for a long time. I''ll definitely be using Eastwoods Internal Frame Coating on all my personal and project vehicles from here on in. It's just another measure of protection against the Cancer we call rust.
