Amazing Initial Success with half gallon of 80% phosphoric acid in gallon spray wand - Internal Frame Rust conversion to ferric phosphate

 Wow - the inspection camera today was finally showing success on the internal frame rust conversion!! I have some minor skin burns - some blood - on my face and hands - and my left nostril still burns a bit. haha. I was able to spend a lot longer time to get better coverage - as I did the treatment at my relative place - the gravel end turn around. So I will do the 2nd half of the gallon when it warms up again.

This is very exciting to finally get results (over all an estimated 70% conversion of rust!!) and of course the inspection camera keeps me honest about the condition of the internal frame rust.

I read online that people did not have success with the Eastwood internal frame - what do they call it - ?  "coating" - yes I posted research yesterday on how the phosphoric acid is much better than the tannic acid.

So I will still do the Eastwood coating - as even though it traps in moisture the underlying Phosphoric Acid should maintain prevention from corrosion - along with the tannic acid in the Eastwood "coating."

So I will make sure to drive a lot to dry out the internal frame before I do the Eastwood coating.

So getting the inspection camera was a definite game changer and based on this inspection this morning - I realize that my next strategy is to focus the gallon spray wand on the top and top corners or sides - of the internal frame. 

So that way the rust on the top will get converted better and still run down to the bottom. The Bottom of the frame is definitely 70% better if not even better - maybe 90% better on the bottom of the frame.

Yes I better drive again today to dry off the internal frame hopefully - to prevent any flash rusting as water is a byproduct of the ferric phosphate chemical creation.

Actually since it's almost 20 degrees colder today - I think I'll use the hair drier - I can get an extension cord or even just use my portable generator - to walk the hair drier around as I stick it in the access holes in the internal frame.

So I did the hair dryer - for a minute in each hole - to help dry it out.

Then I did another inspection camera check on the other side of the internal frame. I did not spray it as much as the driver's side and sure enough - there is a bit more rust. 

But the internal side of the frame is ready finally for rust reformer paint - so I will do several paint layers today.

I do rust converter paint and then the metal primer paint and then another layer of rust converter and then the extreme chassis epoxy.

So I will do that on the "back side" or internal side of both the internal frames - that stretch that had the paint previously scraped off from the mechanic using the Lift.

OK so first layer of "Rust Reformer" paint. I should have just for the 2nd layer of Rust Reformer paint on top of the "Clean Metal Primer" - Rustoleum.

Then the "extreme black chassis" lacquer epoxy heavily dense stuff.

I'll try to do two coats of that. 

So the idea here is to prevent the scraping off of the paint if I ever get the car lifted up again - as it will obviously need repair work done.
