Does anyone have experience with this, or have another solution (that ISN'T liquid)?
Yeah...dont use one!
I couldnt keep the muffler gasket in my Super Tigre for nothin. I even tried other stuff. The instructor at our field told me to just not use one,as they never last long anyway. I took it out and everythings worked great ever since. I dont even think it leaks.
Not sure everyone would recommend this,but I know it can be done.
