Reiff Heaters ( 3 hrs )
Installed 
Reiff Heaters ( HotStrip Oil Sump Heater System, item HSS) so I can preheat in cold weather.   Reiff provides good 
instructions.   After trial fit to confirm location for each heat pad and the thermostat, I removed the paint with acetone, then scratched surface w/ scotchbrite.  The included epoxy is thick and tacky...kinda challenging to "corral".   Requires at least 48 hrs at 75 deg.
