It comes in a can large enough to dip brake lever tips in, a couple dips after letting it dry in between makes a smooth durable surface. Don't know about handlebars tho, I have the old Hutchinson formed rubber on the handlebars of one bike and it isn't all that great to hold onto and it is waaay stronger than the PDip. I have thought about putting Plastidip on the chainstay of my mountain bike to catch the chain slap, but I did do bicycle rear baskets with it. PD doesn't stick unless you really clean and prep the metal. I scrubbed a new basket with steel wool and acetone, then a tack cloth followed by spray paint for stoves/refrigerators/appliances. After a week of drying, I sprayed the PD on it and it has lasted three years of grocery shopping, and carrying bocce balls in a bag with a small cooler to the park. But it lasts about 6 months on any tool I ever have put it on.
