Exactly they sell release compound spray on wax that dries to atom thicknesses but is high dollar. I bought some WWII developed german epoxy to fix the lead screws in my mill and a kit with wax 30cc's of epoxy and sheilding puddy mixing sticks etc was $75 bucks. I fixed only the y axis and now 2 years later wish I would have done the x and z at the same time but wasn't sure if it would hold up. Now the y has no backlash to speak of think 4 decimal points. I can test with a dial indicator and sometimes it reads or doesn't and my eyes stat to get blurry. The z and x has maybe .008 to .01 mm Which is fine and the computer compensates and you only notice on the read out but I know its there and drives me nuts.
If anyone ever needs any for a cam cap repair, high tolerance fit, fancy machined piece etc this stuff is what you need, self lubricated and has zero air entrapments and can be machined like steel or aluminum. Really crazy because you pour it like water or oil. I guess its about like 5w30 when mixed then by the next day is like steel. I would actually like to build a complete firearm out of it just to say I did but you would spend thousands on materials. This mixed with carbon fiber and kevlar could stand up to anything.
All the engineering specs are here you can download the manual and read The Guy there actual fixed his friends daughters car with it , she had a burned up cam cap and they repaired it then years later she sold the car and it was still going strong.
I'll probably buy another kit in the summer and do the z and x and may do the shifter in the car at the same time. Just my lead screw used only about 6cc and I was left with a syringe tube full of extra.
