ive had a mark on my bonnet for ages where some bird sh@t on it
ive tried all kinds of polishes and loads of washin and it would never go away, i thought it had burned through the laquer
turns out it hasnt, and i got somethin to remove it
so if you have any bird poo marks, tree sap, tar, or anythin like that on your pride an joy
get some Turtle Wax Bug & Tar Remover.........its the nuts
