bambislayer:- if it's on the tank, as often as not it's a seam, use up gas until you're below leak, get some resin with fibreglass shards, clean area around leak, mix resin and hardner and apply straight away, if you cover the patch with polythene it won't look too rough, when resin is dry, it takes about 1/2 an hour, remove polythene, let resin cure for 24 hours, top up tank and check to make sure that it's not leaking, then give it a quick squirt of paint or "stoneguard" to tidy it up a bit.... callie
