I am very attracted to build stuff in stainless steel material (Probably
as I hate to paint stuff, and hate rust). I have had problems numerous
times with galled screws which has set me back several hours
and sometimes I even had to start building from scratch.
We are getting these pain in the .... door sellers at work selling all
kinds off chemicals, working gloves, magic drill bits at 20$ each etc, etc.
One off these guys convinced me to use his anti seize shock spray. The
product name is Kent, and the specific spray is called Rusty shock spray.
The content in the spray is a liquid with a minus 40 degree F boiling
point, and graphite lubricant. The graphite makes for a very strong lube
film.
This product is really amazing. I have had several stainless steel
threaded parts that nearly locks up before I am applying the graphite spray.
A couple off seconds later the graphite spray has worked its way between
the threaded parts and I can start freeing up the bolt by turning it
intermittently
in clockwise and anti clockwise direction. Pure magic!
Do stop turning the bolt at once you have to apply more than normal
force to turn it, or even better give it a shower before you even try.
Today I called this seller asking him to come by and fill the empty
chemical shelves at work.
I am pretty sure you'll find similar products in the US. Highly recommended.

Rusty Shock Spray
A multi purpose rust penetrant with fast freezing abilities.
* Graphite based - Excellent lubricating abilities
* Freezes down to -40ºC - Shocks components into releasing their bond
* First class penetration abilities - Penetrates into the component to
deliver lubricant coating
* Works on rusted and seized components - Multi use product
* Silicone free - Body shop safe
*Applications*
Rusty Shock Spray can be used for all rusted or seized nuts, bolts,
screws etc. It is particularly effective on exhaust mountings, manifold
studs and nuts, suspension mountings or other fasteners where exposure
to weather or water promotes corrosion.
Rusty shock spray works by freezing the component which causes
contraction and this act then “breaks” the bond that has been preventing
the disassembly of the item.
