While we wait for 09112 to finish up unsticking/ overhauling the Allis and need's tune-up and paint tips,let's discuss why people have conflicting results when it come's to best products for various perpouses. In the case of freeing rusted bolts,this is what I believe. Acetone/lacquer thinner carry's a bit of lubricant into rust and in turn allows more and larger molecules of lubricant to follow. The action is similar to a wood splitting wedge,progressivly larger molecules following smaller ones into tight quarters. If that is true you might ask why some smart cookie doesn't package and sell this magic stuff. Actually they did until lawyers took over desighn and engineering in manufacturing. WD40 was mentioned so let's take it as our example. WD isn't the same as it was when you wasted your dad's on your bicycle chain. How many of you remember when dad used WD as starting fluid? Try it today,it doesn't work. Some fool set himself on fire then sued the manufacture,retailer,freight company and the kid next door for his stupidity. WD changed the formula. Remember when dad couldn't find his WD because the can was lying empty where you finished greasing the bike? No problem,dear old dad grabbed his Liquid Wrench,gave the mower a shot,cussed and yanked the rope. There are a few luck dogs with the same can of lubricant they been using for years and it works well. There's others that haven't messed with rusty stuff since getting a well paying job but recall how well xxxx brand penetrating oil worked and will tell you about it.
