china wall sealant??

There used to be a carburetor cleaner spray by that name, could go to the local warehouse (it was made somewhere around here besides) and there was no better.
They had penetrants I believe too, I think it was made by a company that used to be called "herdors, inc" out of (somewhere around) Mokena IL. IDK if this was a regional product or available more widespread
Are you sure it wasn't based in middle georgia... lol...
