Personally, I prefer waiting a few days for an online order of the actual substance Boberg recommends. I found mine, a pound jar, at an electric supply (??!!) in the Midwest, for half what a local industrial supply outfit charges. Took maybe 3 days to get here. And I don't have to worry about whether a substitute is ok or not.
If you look, it is on the approved list.
I have LPS on order, i just wanted something to hold me till my order arrives.
Sorry about that. The list I had seen only lists LPS.
