"... Available from PinRestore.com. Or get it at precisionreloading.com/superlube.htm (get the 3 oz gel tube part# SP21030). I heard it is also at Lowe's as "Super Lube Synthetic Grease" (barcode 082353210305), but again it's not on their website. Also rumored Harbor Freight stores sell it, but again it does not appear in their website. "

"There are additional problems in this design that can cause non-dropping targets, as David Gersic explains. When reassembling the target bank, the little screws that hold the plastic rails to the metal body and that hold the wiper circuit board to the plastic rails can be over-tightened. This crushes the plastic rail just enough to drag on the targets and keep them from failing. If the drag is not too bad, the screws can be loosen. Or a shim of plastic can be fitted to give the targets more moving room. "
