Rated 2 out of 5 by did not work on oil pan This product did not work on a crack on an oil pan. The pan was drained and followed instructions to wait for it to set. the material fell apart in a short while and did not stop the leak. September 28, 2016
Rated 1 out of 5 by Can't I give zero stars? Total waste of time and money. Followed instructions. Didn't work to attach pipe to fitting, didn't work to repair weld on trailer, didn't stay on rifle California button. Scraped, cleaned and prepped. Waited 24 hours to use. Failed all three times. Manufacturer has not replied to my inquires. I would suggest that Pep Boys discontinue selling this product as the manufacturer does not stand behind it. August 9, 2016
Rated 5 out of 5 by Products works as advertised Blue magic thermo steel worked perfectly on my 2000 Saab 9-3 SE muffler.. Had pitted areas of rust and Blue Magic went on easy and thoroughly covered the pitted holes.. Easy to apply and has held up as advertised.. November 10, 2015
Rated 4 out of 5 by good value, seems to work well for quick patch Hole in the exhaust between Catalytic and flange. Seems to seal the hole well enough. I used this to plug the holes and then clamped a section of exhaust pipe around it and it has been holding for a few weeks - it was good enough to get through inspection so worth it for that alone. might be easier to use if it was a little thicker like a putty.
