WHERE was this when I lived in earthquake country!!!!  I was just shown this product by a fellow full time RV neighbor.  Cool stuff!!  If you want something to stay put going down the road in an RV here it is.  It is similar to rubber cement which means it will just rub back off when you want it to but it is clean and doesn't harm anything.  It doesn't take much at all either to hold it.  If you gel a vase lets say or a cup to the table,  It is solid!  To remove it you need to give it a twist.  Nice!
