Reliable, Clean, and Powerful Adhesive—Great Value
I’ve tried a few spray adhesives before, but this one stands out. The spray comes out in a clean, even mist—no clogs, no mess—which makes it super easy to apply precisely where you need it. I used it on a foam board and a piece of lightweight fabric, and both bonded quickly and held strong. It dries clear, doesn’t warp the surface, and there’s barely any chemical smell. Compared to other brands I’ve used, this gives better control and a more professional finish. For the quality and performance, it’s a great value and a permanent fixture in my DIY kit. Also was pretty safe got on my hands and washed right off.

Dirty Mass Air Flow Sensor
2023 Honda ridgeline MAs Air Flow Sensor was dirty. Gas mileage down 3 to 4 mpg. Sprayed and reinstalled. Mileage back up to usual. Still have plenty for other jobs. Good stuff. Good price. Quick and easy.

Did not help
Cleaned my Honda Ody MAF with it, and did not make a difference. It may not be the cleaner's fault, maybe my MAF is too far gone. I should try it again ( soak and clean with compressed air?) .If it works the second time, I will update the review

Excellent product that works exactly as described, and is highly recommended by alot of people in online forums related to auto maintenance/repair.After cleaning my MAF sensor, I noticed a 2mpg increase as well as a little more power during acceleration.
