Fixing a scratch in an otherwise good lp


I seem to remember a method for fixing a scratch in an otherwise precious
lp which caused the stylus to jump. Does anyone remember it?What are the cautions?

 I have found that the best way to cure those omnipresent skips and scratches on my LPs is to duct tape a medium sized lead fishing weight  to the tone arm directly above the cartridge. Most of the time it will force the stylus right through the damaged area, reshaping the groove and eliminating the skip. It is important to thoroughly clean the LP afterwards to remove all the resulting vinyl shavings!
