Hi a mate of mine give me some tar for my brakes, i have little left so i found some on the road where a crack had been repaired, i heated the tar up and moulded it into a ball ready to use on my rim, when i went to used it i rubed it on my rim and i doesn't seem sticky enough to stick, i heated it up with a lighter until it started the bubble and then tried rubbing it on my rim but it cools every quickly and wont stick to my rim, have i dug up the wrong tar or am i doing something wrong ?
i dug the rights hand side one
