WD-40 might help.
Did you let the WD-40 soak for awhile? Like 20 or 30 minutes? If so, then I would give the goo gone a try, but it too needs to soak.
I don't think either of these products will harm the gun. I know Lowe's used to sell a large bottle of it.
Have you tried uncoiled rice?
Throw it in a fire, fire solves everything.
I've never used goo gone as I've always had access to more commercial grade stuff. Beyond trying a 3M adhesive remover, I don't know what to tell you.
How do you forget about fire?Duh,
I forgot about it. I grew up in my dads body shop and worked un many shops. I've used it many times. Thanks

Selective memory. LOL. I have fanned the flames more than Richard Pryor
That looks like handy stuff. I'll buy some of that just to have around.I use something called UN-DU with fantastic results. It is similar to Goo gone but seems to be more specifically designed for things like adhesives and stickers. I always have a bottle or two on hand as my two year old loves to put stickers on anything and everything.
