Resin can stay moldable for quite some time. It's liquid but super viscous. If the tree hasn't experienced the heat of the sun, then it'll stay in place up to a year or five. Solar heat melts it and the wood on the bark will draw it in like a sponge.
If it hasn't changed in a year time, then it's probably not actively secreting/oozing. Inspecting it up close is a good idea.
You can dap it with a sponge you've dipped in turpentine, and it'll dissolve slowly. Just make sure the sponge is slightly damp with turpentine and doesn't drip. Turpentine originates from pine resin, but the roots don't like organic solvents. So make sure you don't allow any turpentine to hit the soil. Some paper towels stacked in layers can help you prevent that. Other solvents will work too, but they can also do more damage. Best to just use the heat of the sun next summer. At 30 degrees C it'll become as soft as hair wax.
