Must be southern pine sap is tougher than white pine. That's what I have and acetone takes it off very easy, then a quick polish job and yer good to go.

Sorry about that... posted before I was ready... not sure how to delete. Here is what I intended to post...

I had this issue with a Bayliner I bought- parked it under a pair of pine trees in the back yard for a year and by the time I realized it was a problem; I had a mess! Tried everything listed above (except the butter... may have to give that a shot next time) but what I found worked best was waterless hand sanitizer. Buy the big pump bottle from a dollar store and use it generously- I put a big dollop of it on the pine sap and covered it with a paper towel for a few minutes then just a little rubbing took it right off. It's best to use paper towels because that pine sap is a mess no matter what you do to it, and I didn't want it on rags laying around the shop.

I wasn't hacking on you and by no means do I think you're not smart . I myself have been there and done that . Hot water n little compound will take it right off ! Sorry to come off like a dick ?

You can use a green scrubby.... Whoops, that's a bad idea. My wife learned that one the hard way when we first started dating. Luckily it was her car and not mine. I still cringe when I think about it... Hope you find something that works. I like the bug and tar remover...

I have tried a lot of things getting tree sap off the boat and the best thing I came up with is this.

Rob, It's all good! Let's face it, parking under a pine tree with only a cockpit cover ain't the smartest thing, but at the time, I had no other options.
In a lot of trial and failure, I DID find something that worked great, and I had it all along.
I found a can of GM weatherstrip adhesive remover on my shelf from mo old dealership mechanic days (almost 30 years ago). A well soaked rag, let the juice do the work with minimal rubbing, and got em one tar-drop at a time.
I then hand washed the whole thing with old school hot-soapy water. Covered the boat and tomorrow I'll pull out the buffer for polish & wax.

Excellent news. Nothing worse than looking at you're stuff. N seeing anything but what you want to see. Good luck. :-)
