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

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.

Great item, great cost, quick delivery !!!!

Zero points really , doesn't work, sprayed it on a steel bolt stuck in an alu head...1 minute maybe, with application in stages, barely frozen, I used an air duster, did 10 times colder, but no bueno, ended up welding a nut, free in 30 seconds, save your money... no penetrative agents in it either from what I could tell !!! Junk.

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.
