Always TRY with the product that is less aggressive.
Use the shellite in a well ventilated area, and use a desklamp, shining on an angle where you can see where you need to rub the residue off.
Goof Off is aggressive, and is a last resort for me.
Thanks for the good advice Nino
Well, PG sounds like your armed and ready to go! I hope to see a new resto thread started soon!
