    Buyer Beware
    1 Star
    Buyer Beware
    I had 2 small leaks within my automotive A/C system, both in areas with no moving parts, best suited for this product to chemically seal as designed. The leaks were identified with a Halogen Detector, considered to be too small easily diagnose with UV Dye. Based on the detectors leakage sensitivity level a leak of 6 oz/yr. was detected in the evaporator (looks like the evaporator was leaking in the center out of multiple areas) and 3.5 oz/yr. in the condenser (right in the center of it). Both pieces would need to be replaced so I figured this product would work.After applying a vacuum to the system, I first started with the A/C stop leak, applied the product as directed, dispensing the entire contents first. I followed this by charging the A/C system with refrigerant to capacity. Over the next 2 weeks I used the vehicle regularly with the air conditioner. After I re-verified if the leaks were still present, I found that the leakage rate in the evaporator was within the same leakage rate zone (4-6 oz/yr.) , while the condenser, may have been showing false positives, likely was still leaking, albeit a very marginal rate < (1 oz/yr.). I considered this unsuccessful.When attempting to call upon the product's well stated guarantee claim with the manufacturer (Blue Devil Products), I was ultimately met with this email:Grant-You may have seen on our website under the Warranty/Returns tab: "Any online purchases made from unauthorized re-sellers are not warranted by BlueDevil Products." Unfortunately, we are unable to honor the warranty for your purchase as we can not access your order through our Amazon Seller account.You may contact Amazon direct at 1-888-280-3321 to obtain your refund. Be sure to have your Amazon order number available when you call.Sincerely,Apparently, Amazon LLC is not an authorized re-seller since BDP has their own storefront on Amazon. Additionally, I inquired which retailers were considered authorized retail outlets; after which I was immediately met with supreme sarcasm that all major automotive retailers: AutoZone, OriellyAuto, NAPA (basically the typical brick and mortar store) are all authorized, as well as WalMart. They also kept redirecting me to see their Warranty and Returns page like as if I did not get the Memo. Yeah, since that is my primary goal, to go and decipher a company's red tape and determine every condition in which their warranty does or does not apply. To me, it sounds like a bs scapegoat to wiggle out of that guarantee so proudly slapped on every piece of marketing material they own. The correct answer would have been, "we are sorry our product did not work, could you try giving Amazon a call first and if they are not able to refund you directly, give us a call back and we will make it right! Does that sound good to you?"So if you plan to purchase this snake oil, make sure you do it at a brick and mortar store, or directly from BDP. I was gravely mistaken to think this product would work anyway. To put it into perspective, if DuPont, one of the largest chemical companies in the world, creators and pioneers of most refrigeration chemical technology has not come up with a viable leak sealer with their massive R&D budget, then most likely, neither has anyone else.Note: Amazon was nice enough to cover the warranty (refund or replacement at your discretion) for this product, and will do so for 365 days from the date of purchase. The Amazon representative stated warranty claims are charged back to BDP.

    1.0 out of 5 stars Can't make a can so save their lives.
    Reviewed in the United States on August 27, 2023
    Worst product ever. Before you think I'm a noob or don't have a clue, I've been servicing cars professionally for 35 years. I had just replaced an A/C from the compressor to the condenser and everything it between. After putting the system on vacuum for 2 hours I usually let it sit for about a half hour or so to check for leaks. After everything checks out I let the car idle until normal operating temperature and start to fill the system to manufacture specs leaving room for a seal sealer as preventative maintenance. I do caot all the O rings with oil but enjoy a little peace of mind having something circulating through the system. Following the directions on the can, absolutely nothing worked. Would not seal to the port. (All R-135A low pressure ports are the same) depressing the trigger on top of the can didn't work either. Have to push on an angel from the corner and then it's hit or miss until the nozzle pops off. Center of the button is a no go. As for the quality of the contents, I'll never know because it can't be used. The small bearings that are supposed to lock onto the port are too depressed to lock and don't pop out to hold no matter what position the spring loaded collar is in. A longer tube would also be appreciated so it can be shaken while filling as the directions state. Very frustrating. I will never purchase again and will steer others away from this product.

    Reviewed in the United States on February 8, 2017
    After watching ChrisFix on Youtube, I was inspired to try and fix my AC on a 2007 Accord. First, I had to determine if a leak was the cause of my AC woes. I purchased an AC gauge and used it determine what my pressures where. I found that my pressures were extremely low compared to the Honda maintenance guide so I added some UV dye and r134a so the compressor would circulate the dye. I purchased an inexpensive UV flashlight from Home Depot and didn't see a leak. After a couple of days of using the AC, I went back under the hood and noticed a leak on the high pressure tubing coming off the compressor. It was leaking from the crimp that transitions the aluminum tubing to the flexible rubber hose as indicated in the photo on the right. The leak continued to grow so I decided to add the Red Angel and slowly added r134a to the prescribed pressure level while checking the blower temperature. Over pressurizing the system can damage the system, so I wanted to be very careful. I found Red Angel after researching various forums and found great reviews. I didn't want a product that would harm other components that would be really expensive to replace so this seemed like the most conservative product to use. After following the simple directions, I noticed after a day that the leak was still growing. I cleaned off the dye from the crimp and used the AC for another couple of days. After a few days, I noticed the leak was still present but it seemed to slow down. After a week the leak completely stopped. The picture on the left is the residual dye and it hasn't grown since. The AC has been working great and I now am confident that the system is sealed. Great product that saves money. Note: This isn't a miracle cure. It will only work for relatively minor leaks. If the hose is torn or the aluminum tubing is cut beyond a pinhole, the leak will not stop. You will either have to replace the part or patch the damage. Also, be patient with the product. As I described and confirmed with technical support, the product will not seal immediately. It takes awhile for it seal.
