Blue Devil Head Gasket Sealer Review

bottleTHE GOOD: This Gasket Sealer is a quick solution for problems such as small leaks and minor maintenance jobs. Repairs can be very costly, and that is why more and more people are looking to solutions like this.

It’s fast-acting and easy to use and you’ll save a small fortune in services by applying some of this sealer.

THE BAD: While the product generally works as intended, according to a few consumers there are a couple of things that are not perfect about it.

For example, a few buyers mention that the directions are a bit confusing (although we personally don’t agree with that). Also, a couple said that the bottle does not let you see how much you’ve used (which we do agree with), so you need to be careful not to pour a bit too much sealant over your leak.

THE BOTTOM LINE: If you’re careful when applying it this product is a great choice.  It’s good value for money, does a very good job, and provides a permanent repair to a number of head gasket problems.
