I have a tan fabric top on my T/A, and the other night when i went out to my car i noticed there were 3 small drops of tree sap on the top. I immediatley took it to the coin op and washed the top, and i tried to carefully remove as much of the sap that i could without making it spread or pushing it into the top. I also used my RaggTopp cleaner on it, and tried to wash it off several times, and i thought i had suceeded. Well today i go out to my car and notice that the areas have a black crusty type material on them where the sap was, and i tried to get it off but nothing is working. Is there ANYTHING i can do to get this off? Any suggestions on what i need to do? It sticks out like crazy...
