"I saved my customer over $750 on his rear main seal leak with the BlueDevil and have only seen him twice for his annual oil changes, the truck is running great!" Harry - Flint, MI
"My rear main seal was leaking slowly and I could not afford the $1,000 quote that my mechanic gave me to fix it, BlueDevil saved me $980 and I have been driving the vehicle for 5,000 miles without a drip, thanks for such a great product!" Bill - Buffalo, NY
"I have gone three for three on fixing rear main seals leaks with your product, each bottle fixed a different car, I don't know how this secret has been so well kept but I'm telling everyone I see to try it out! " Ron - Melissa, TX
"My name is Brad and I'm an ASE Certified mechanic. I bought your BlueDevil Rear Main Sealer about a month ago. I poured about half of the bottle in my in-laws' 95 Dodge Neon that leaked about 2 quarts of oil every 3-5 days from the rear seal. About 3 days into adding it I noticed the leak slowing. By the end of the first week the leak has completely stopped! That was 3 weeks ago. I'm very impressed with this product and will recommend it to anyone that can't afford to fix it! Thanks again you guys saved me about 7-10 hours worth of labor! "Brad Ferrier - Clearwater, FL-bd
"3/3/11 I must say, your rear main seal worked for me. I found you on line and in that moment felt some hope. I am a mail carrier and drive a 1995 jeep, which had developed a pretty bad oil leak. I narrowed it down to a leaking rear main seal. Desperately needing a miracle, I ordered your product. It took a couple of days, and I actually did a second treatment. Wow, the leak is gone like magic. I have already told others about your products.Your product fixed my problem; with the extreme driving I have to do each day, it's a perfect solution for any normal driving use. " Randy Vickrey - USPS mail carrier
" Folks if you've ever thought testimonials were fake, think again. I recently commented on BlueDevil Gasket sealer and I'm about to on the BlueDevil Rear Main Sealer. I'm a 24 yr AF Vet who really does live in Fairview Hts, IL and struggles like most to keep older vehicles driveable. USA Sealants you've done it again! 6 weeks after using BlueDevil Gasket Sealer for coolant leak, my 174K mi Lumina had simultaneously been leaking oil so I tried your Rear Main Sealer in oil... "BAM" 2 weeks later and oil dipstick has not moved from "full" mark! I don't know what your chemical engineers are doing, but don't let them change the recipe. By the way, 3 months prior to this I tried using STP Oil Stop Leak, even tried a second can a month later...wow, that was a waste of money. USA Sealants I want to personally thank you for the money you have saved me...and with economic situation the way it is...you guys have been a savior. Folks, their products REALLY DO WORK! "
