Did not work
It's a bit like pedaling snake oil, once a head gasket has blown, it's blown and there's nothing you can do about it, I had a small leak where one cylinder was leaking exhaust gas into the cooling system, I was getting about 100 miles on average before having to top up as it was expelling a small amount through the radiator cap, I had a 350 mile journey to get back home so decided to try this snake oil and had it delivered to an amazon locker. The sealant came next day and I put it in the radiator, a thick treacle like substance, I thought it might help but I could not have been more wrong, the coolant frothed up and expelled the entire coolant within 30 miles spraying a thick white waxy coating over entire engine bay, really nasty mess, needless to say I won't be trying this stuff again. Wonder weld left me wondering alright, wondering why I even thought it might work.

Love this stuff... got me out of a pickle a few times. This product is alot stronger and heavy duty compared to the usual rad weld. Looks like Bovril and smells awful but it does the job. Ive never used it to attempt a head gasket repair but in my experience it will seal all the usual problems in vehicle a water system. Recommended.
