Been a long time, and probably with the earlier product, but IIRC I just
sprayed it over whatever was left of the original dry lube. I probably
scuffed the inside of the canister with Scotchbrite or emery cloth and
cleaned it with brake cleaner. Probably did a couple coats, just like
any other paint. I remember I had to buy 2 cans of it--and used about a
tenth of a can--and had to pay a bunch for hazmat shipping. The
remainder was unusable after a couple years.
In hindsight I think I probably didn't need to do it, as the original
coating appeared to be intact and the piston wasn't sticking.

Michael Salter was kind enough to inform me that the vacuum chest
of the servo is steel rather than aluminum, as I had stated. <br>
<br>
So, what follows is Sandstrom's application protocol for steel:<br>
<br>
"Application on steel. Pre-clean the steel surface with aliphatic
naphtha or any other EPA compliant cleaner that sufficiently<br>
cleans surfaces to pass ASTM F22. Sandblast the surfaces with

<br>
Any comments from those who may have used the Sandstrom dry lube
products in the past?<br>
<br>
Thanks.<br>
