Re: [TowerTalk] Ospho & Cold Galv

Sounds like the same chemistry used in the Rustoleum primer I used on keel 
bolts and nuts. Went on white and turned a deep purple/black and in the case 
of the Rustoleum product it was a primer.

There is another rust eating product you may not be aware of called Enrust. 
I've used it several times with great results.  It's similar to Ospho, but 
it's not acidic or caustic.  Looks like milk.  You just brush or put in a 
spray on windex type containter and spray it onto your material.  Where it 
touches rust it will turn black from a chemical reaction.  Where it doesn't 
touch rust it will stay white and just kind of drip down.
This worked great on an old lawn mower deck I have and more industrial type 
things like farm equipment.  I used it on my truck where it had some rust 
spots from getting hit with acid at a refinery.  It worked great on the rust 
spots, but overall it didn't work out so great with the clear coat.  I have 
a white trush and it left a rust colored area over the clear coat.  Mainly 
because I reused the same brush from my lawnmower.  Live and learn.  After 
all your supposed to paint over it, so it shouldn't matter.
Here are some usage tips: don't get it on your hands, they will turn black 
and you can't scrub it off.  You just have to wait for the skin to wear off. 
Only use a brush once, once you've finished for the day, throw it away. 
Don't dip a brush into your main container.  Pour the Enrust you plan to use 
in it's own container and dip your brush into that.  Your brush will bring 
small amounts of rust into what you're dipping it into and contaminate it. 
You don't want to contaminate the entire container.  That's why spraying it 
on works so well.  When your done just paint over it.
I purchase it locally at a commercial automotive paint store.  I covered my 
entire old craftsman lawn mower with about 6 fl oz.
