I searched but didn't see any threads about this. What do you guys think: http://shop.truegoo.com/product.sc?productId=3&categoryId=5 Anyone use this? Looking for a sealant for both road and mtb stuff. Going to be trying to put the stuff into the presta valve stems. Wish me luck. Wanted to make sure this stuff was ok before I purchased. I've been using stans which worked well on some tires but not well on my slant six TLR which continues to need to be pumped up every few days, even riding daily.
