anybody have any good ways to remove old pen stripping from a Legacy ?

Use a hair dryer to heat up the pin striping and just pull it off. Use some goo gone or something similar to remove any remaining adhesive. You'd probably want to use some polishing compound when you're done (after you've washed the car to remove the goo gone) to help remove any built up wax or debris that has created a lip.

 

Be aware that the paint not covered from the pin stripe has probably faded, and you will likely be able to see where the pin stripe went.

What he ^^^ said! You can always replace it with new if the fade is obvious, a steady hand and a good eye and anyone can tape a stripe.

 

If the pinstripe is paint ~ you can 'color sand' it off... but this is a LONG and TEDIOUS task and not for the faint of heart.
