A broom handle and a hammer works wonders... then get a headlock, and breathe a sigh of relief at never having to use a broom handle and a hammer again every time this happens.
I used to use tar all the time, never really had a problem with it sticking unless id put waaaaaaaay too much on. Makes a handsome noise though... kinda makes you look less smooth than you are if that makes sense, due to all the noise.
Lol, i do that! Look at the bike, and say something like 'shit, wheres it gone?!' and look around the bike concerned for a bit. Although have just got a justice, so not sure if the weird moto type saddle thing counts as a seat
