Just thought I'd stick this out there. Been using it for a long time, but some people seem to never of heard of it. Orange can, avail. at NAPA for about $10-11 a can, but man does that shite work. Bust loose old rusty anything. 3x the cost of WD-40, PB Blast, etc.. = 3x as effective. Well worth the cost. Also picked up a can of that "Seafoam" I read about in a post. Running it through the 96 GS and my 93 F-150 today, will post if I"m as happy as everyone else is with it....
here's what it looks like...
