BlueDevil Head Gasket Sealer: SPOTLIGHT
"My Girlfriend gave me a 1998 Cadillac SLS as an early Christmas present in November, and I was concerned with the Northstar engine problems. Well of course the car overheated the first time I drove it, and the dealer wouldn't do anything. I decided to try the Blue Devil Head Gasket fix, Figured 65.00 was better than the 2-5000.00 fix. Worked like a charm. Drove the car to Las Vegas over the holiday and ran like a Cadillac Should. I have and will continue to recommend the product to anyone that has an over heating problem. Great Products that actually works." - Scott
"A mechanic at triple A recommended your product verses a $1600 head job. I have tried products similiar to this before, with no luck. As you know, im sure this product workes!!I will recommened to everyone, going to get my son a bottle this weekend.Thank you so much!!! BLUE DEVIL IS GREAT" - Danny
"Guys, Not having anything to lose and everything to gain I used BlueDevil. I initially was not very impressed. I drove the car twenty miles and had to top it off with water. Your recommendation of leaving it in is a good one The longer I have left it in the better it works. I checked the fluid level last Saturday and it was within normal limits. I have been running the air for three days and so far so good!! At this point I think Blue Devil is a winner. Thanks Soo much and Pass along my kudos, Roy M. Munson Pine City, New York "

"BlueDevil works! It saved me from having to junk the car altogether or tearing down the engine to replace the block. The car is so old it just wouldn't be worth that kind of investment. Finally, a product that works as advertised. Thank you!" Darrell - Auto Parts Store Manager

"What a product! The BlueDevil products are amazing. It helped stop my power steering from leaking on my 1998 Land Rover Discovery. BlueDevil is a great and easy to use product. It saves time and money, and it really works! No more costly repairs and time lost at dealerships or mechanics. Just follow the directions, it is just that easy! No more black spots on the driveway. I would recommend this to every do-it-yourselfer out there." B Rosenberg
"Just thought I'd drop a note of my experience with BlueDevil Head Gasket Sealer, the yellow label. I know it says that it's not recommended for the North Star motor but I had to give it a shot. I think the bottle states that because the North Star usually has head bolt issues and a sealant may be a tough fix. Anyway, I had a shop do the treatment (they weren't thrilled about it, but the they did it) and made sure that they followed the instructions explicitly. It worked! More than a 1,000 miles later it is still holding. That and consider I live in Phx, AZ so may average outside temp for the last 1,000 miles has been over 100 degrees and I'm pretty impressed!! I don't think I got lucky, I think conditions were just right. My leak was very slight, we followed the instructions and the circumstances were right. Thanks, great stuff." - Gino Niccoli - Phoenix, AZ
"I have been pushing your products since i have used them and am convinced that it is god in a bottle.IT performs miracles.I just put Blue Devil in my corvette where i was losing a gallon of coolant in 70 miles.Within 5 minutes it was healed.Before i am done i'm sure i'll have all your products in my car.Follow directions and it works. "
Brian Lane - Charlotte, N.C
"I used the Head Gasket Sealant about 3 weeks ago. Carefully followed all directions. I am very pleased that the car is running beautifully. The engine has GREAT power and no white smoke. The car has been driven approximately 200 miles. Question: How many miles must I put on my car before I drain the radiator, put in antifreeze and replace thermastat? Thank you so very much for saving my car!! " - Tara Webb - Durham, NC
"I followed the instructions for the head gasket sealant and it worked ($60.00). I previously changed the head gasket and water pump, and other relative gaskets needed, dropped the oil pan and checked the seals on the piston sleeves. No sign anywhere of a crack or leak so I figured it must have been the head gasket leaking water into the oil somehow. Well, even after all this effort I gained almost ½ a quart of water in the oil in about 10 minutes of running the tractor up and down hill. (1954 Farmall 230) So I tried this stuff I have run it with a 5’ bush hog at ¾ throttle for over 2 hours and the engine oil is clear. " - Bob Warnock - Avon, ME
"I used the head gasket and block sealer in a 3.8 engine and it's still not filling the crankcase with coolant. I can't believe how good it worked for a friend's engine. Thanks. 9/21/2010"
" I just wanted to email you and let you know that the BlueDevil product is moving well. I am having good success in introducing it into the shops I call on. I have learned a lot after talking to my customers about "real world problems" they face in the shops. I have encountered every other type of competitive product out there you can imagine, and even though that may seem initially as a detriment, it is actually a positive because it means this customer is prone to using a product such as ours. I listen to my customer tell me how the competitive product works and then I ask some some follow up questions, such as : Is this product you are using a "permanent repair" ? or are you afraid that a product with solids in it might plug up a radiator or heater core ? I then ask them if there ever was a repair that they were not able to fix using the product they have. After all of this then I talk a little about our BlueDevil product and relate "real world fixes" that other customers who have already used BlueDevil have told me worked. I tell them that a shop I called on used BlueDevil to repair a leaky intake manifold on a 5.3L GM product in the passenger side back corner. Another shop told me that after a Chrysler product came in for a routine coolant flush, a leak developed while in his care from a freeze plug located between the engine and transmission. He did not want to tear half the car apart to fix the freeze plug, and not get paid for it. He instead decided to try our BlueDevil and sure enough after following the directions on the label it worked perfectly, and saved him from a time consuming repair. The best on of all though was a customer who had a 1998 Buick with a head gasket leak between cylinder #1 and #2, that was so bad the engine was hydraulically locked up. He removed the spark plug in cylinder #2 and pumped the coolant out of it. Then he drained down the radiator and pulled the thermostat. The reason he drained the radiator almost all the way down before starting the engine was because the leak was so bad in cylinder #2, that this was the only way he could get the engine running without hydraulically locking it up. He then ( with great skepticism I might add ) used the BlueDevil product as per label instructions. After 50 minutes of run time he shut it down, and reinstalled the thermostat. He then let the entire thing cool down overnight. The next morning they pressure tested the leak, and it was holding pressure. He could not believe it, and was extremely pleased with the results. Not that this was a hard car to do a head gasket job on, but the customer who owned the car was not going to repair the car the mechanical way. I must say that telling these success stories over and over to potential customers has provided the push necessary for them to say yes to my sales offer. You must get comfortable with the proven results, and learn the competition. I never knock the competition in any way. I only tell my customer about how my product is a superior grade permanent repair, and one they can trust and count on by relating true real world testimonials that I have learned along the way. This product belongs in every one of the shops we call on. Thank" Ed Niccum - Carquest
"I love BlueDevil!!! I was just quoted $1100, 1200 and 1300 to replace the head gasket in my 95 Saab 900SE Turbo.. The vehicle would be worth the investment but i don't have the money! I went and got a bottle of BlueDevil for $65.00 and followed the directions and after 1 hour then driving 25 miles and looking at the exhaust there was NO SIGN of smoke AT ALL!!! PLUS... I lost not a drop of coolant and the car ran smooth and quiet!!! THANK YOU! THANK YOU!! > YOU just saved me $1000.00! I will keep your product in mind whenever someone needs a sealer product, I WILL DEFINATLY RECOMMEND BlueDevil and your other products! You have a 100% Satisfied customer... Thanks, Sincerely, Brad Shatuck" Brad Shatuck - Fremont NH
