I just waxed my wife's Subaru Legacy. The tree sap on it is nothing like I've ever seen. I assume it's sap. It feels like it and smells like it but it looks like white glue and the Turtle Wax sap remover I used won't touch it. Any suggestions on the best product for sap? I have not been impressed with Stoner's Tarminator by the way. Thanks for the help.
