ARCCI400 400 ml Crack-It Shock Freeze Release Spray - Blue

I bought this to freeze a stuck bolt in a classic car. It does cool down the metal, i didnt think it was anywhere near -50c and i used the whole can on one bolt in three attempts to release the bolt but it was no avail. The spray didnt seem to make any difference at all. I doubt I’ll use this again.

Had tried several ways to undo a large flywheel nut on a 14HP Briggs & Stratton mower engine. Would not budge. Then applied Crackit per instructions. Then reapplied socket with long extension and hit it with hammer as before but this time it suddenly gave way after which the nut came off easily . This is not the first time I have used this product. I have also used it successfullt in the past to remove a recalcitrant gear box pulley.

I bought this to help while working on an older car and trying to undo rusted bolts and nuts. This was a great tool and combined with a blow torch to heat the nuts then a blast of this spray to cool it to break the rust and lubricate this. It worked very well and certainly worked for me. It is better value here than other stores. Will buy again.

Using very little made the atmosphere very unpleasant. i wouldn't recommend it for indoors.

Works only as a release spray, no better or worse than plus gas.
