Looking for product recommendation to remove pine sap

  • Stoner Tarminator
  • Goo Gone Automotive (NOT the household version)
  • CarPro TarX
    These are designed for clearcoat and very effective for heavy sap.
Soften the tar with HOT water first.
Thanks!

Only problem is, the truck is indoors now (non-heated storage), and there's no way to get it (the truck) warmed-up, and/or having water not freeze on the floor of the space.

I'm also concerned about letting the sap sit there all winter.
