[ihc] Rust intervention

[John Hofstetter <hofs@xxxxxxxxxxxx>]

There was a vendor at North West Roundup named Rust Doctor. He (they) 
sell the latex rust "stuff" by the quart or gallon. Nice display of old 
rusty stuff that they had reclaimed. He, the vendor, said that Rust 
Doctor makes magnetite out of the rust. I don't think he's even close 
to being accurate there, but the stuff that he had reclaimed looked 
very good.

First they put the Rust Doctor on, then several layers of sanding 
sealer to even out the surface and then painted that surface. So, for 
example, they had an old rusty wagon with a piece of it still covered 
with rust, a piece with the rust converted to magnetite, and a final 
painted surface. Looked good.

One of the reasons I bring this up is that I posted just before going 
North that I had used Duro Extend on the surfaces I could reach between 
my inner and outer fenders. Same stuff with a different name as far as 
I can tell. Rust Doctor sells for  $25/qt. and I THINK that is about 
twice what you can find the Duro or its equivalent for  at your local 
hardware store.

However, it was very nice of the Rust Doctor fellow to be a show 
sponsor and if I hadn't already had a supply of the Duro, I'd have 
bought a quart. He had what was to me a really innovative idea and that 
was to use a garden sprayer to spray the latex up into the spaces you 
can't reach with a swab or a brush. I wish I had thought of that while 
I had  the holes open into my fenders. Not rocket science, but I never 
thought of a garden sprayer.

Over the years, I've used the latex and have had good luck with it. 
Floor pans and such are so much easier to deal with by using the latex 
than any other way i know. I also use a Phosphoric Acid compound that 
converts the rust to an iron phosphate that is very durable and forms a 
good paint base. However, it makes me kind of nervous when I'm using it 
because the bottle has large red warning signs all over it. You're not 
supposed to drip it on yourself, and I seem to be a natural born 
dripper. I'm talking about when I paint!
