Great value for the money
We went all over to get some lock tight and found it was really expensive for the size. We were able to get the larger size off Amazon for a better price then the smaller bottles as Ace Hardware or Walmart.Best value for the money

Product works
Great stuff for automotive needs. Bottle is a good size if you use it often on older car/trucks that need some hold on the bolts.
