I know that opinions vary on using flat-fixing stuff like Slime. But I'd like to hear from people who are actually using it.
The only downsides I'm aware of are: * might dry up and gunk up your valve (their website says it's water soluble and that you can just remove the valve core and let it sit in hot water to disolve it). * Adds a little weight to the tire.
Please vote for either "yes, it's helped" or "no, I've had a problem with it." That way we can just get a quick idea of how effective Slime is.
I've used it in the past and had no problems. I'm planning to put it in my wife and kids' bikes and in my commuter bike. All bikes where speed isn't important and dependability is.
