Edit: Still holding proper pressure at 2-months !!! Had a slow leak where my tire went from 44psi to ~18psi over 2-3 days… Dashboard light would let me know every few days that I had a tire problem and I would inflate the tire back up to 44psi… Anyway, I used this product and filled air back to 44 psi and it’s held the pressure for a month already !!!! Be sure to deflate tire to ~15 PSI before adding the product… it only took about 30 seconds to empty the container into my tire with the tire pressure low. Very happy with this product !!!
