Highlights
Quality
I have gotten 1 year to several years by using the product
I had a blown head gasket on my 99 mustang v6 and a mechanic recommended me this product
So far havnet been very impressed but maybe with the second go around ill have better success
I recommend this as a diy product
Packaging/appearance
Was gonna junk it but tried this first
Competitiveness
And i drive that car the way a bmw should be driven
Read the reviews of competitors products and decided to side with the devil
If you have to pay a mechanic youre now getting close to the cost of the mechanical job
