Re: [Chrysler300] 57 - 59 grill U nuts

Thanks Keith.

The reason I use the Bill Hirsh stuff (or POR-15) is because it's designed to adhere to rust. 

If the bolt, fastener, etc. is one that's unique to our cars and can't be replaced anywhere, then I'd soak it in Oxy-Solv, which is a non-toxic chemical that disolves rust and leaves a zinc phosphate coating. I've used this on rusty data plates where wire wheeling would destroy the stamped numbers.

  I may have made it sound nasty, but naphtha is just a really clean paint thinner; and, geez, don't you ever clean your toilet bowls or put oil on something?  This is all ordinary household stuff.  And then tell me please how you get your wire brush down in the U of the U-bolt.  If you don't get rid of every trace of the rust before you put whatever finish on it, you're going to be doing it all over again someday.

    Wow. Sounds like a lot of ugly, caustic chemicals in this multi-step 
    process.

    I would achieve the same results by wire wheeling the rusty nuts (held by 
    vice grips). Then I'd string 'em up on a coat hanger and lightly brush with 
    Bill Hirsh Miracle Paint (which I prefer over POR-15). Let them dry 
    overnight for a semi-gloss black. Or if you want to get creative, wait until 
    the Miracle Paint tacks up, then rattle-can spray them silver, cast color or 
    whatever floats your boat.
