    Good seller, my ordered was as advertised, except for it came in 2 packages 2 different days. This certainly could have been shipped together, as the box was big enough for about 8 or 10 of the extract bottles. Again, great seller, will do business again.

    Great bottle of hand wash. Seller is top notch in honesty, packaging and speed of delivery. I ordered two . Seller made mistake and only sent one ( hey stuff happens you know!) But promptly responding with apology and made up new package with second bottle and I just received it . All is well thank you for having the integrity to deal with this issue professionally. I will save you as a seller for sure!

    I ordered the syrup last week, was tracking the order the whole time, said it arrived but it wasn’t out there - I messaged the seller who immediately offered to give me a refund or replacement, pleasantly surprised! Great seller quick shipping too!!!

    Got a leak? this will plug it quickly well worth the money

    This product works and does not take much time to stop engine coolant leaks.

  • Product Works!

    I was as skeptical just from the looking of these tablets. The car is a 96 Buick Skylark, transverse engine, with the leak coming out just below the crankshaft pully. This leak was dripping at a rate that would drain a gallon in approx. 30 minutes. We put two tablets in, drove 20 miles, let is sit for 1 1/2 hours. Started up the car and the leak was gone. 3 weeks later and still no problems.

  • Great Product!!

    Got the GM sealant tablets. Read all directions. My vehicle does not have a radiator cap. Crushed tablets, dissolved them in warm water and poured in coolant overflow tank. Drove around for forty minutes. LEAK GONE. Great product!!

  • No Coolent Leaks

    Restored 1987 Buick Grand National not leaking Coolent. I put the tabs in a shop rag and gave them a couple of whacks with a dead blow hammer and installed the results in my lower radiator hose; the concept came from the Buick Grand National forum with the idea being that the tabs would go through the engine block before they went through the radiator - no leaks.
