Cleaning Pier Gunk off side of boat

[sslocum]

I was try to clean what looks like creosote from side of boat where it rubbed the pier. I tried black streak remover and other products from west marine but none of them worked. My nephew works at a marina and told me to use fingernail polish remover, it worked like a charm.

Re-wax, as fingernail polish remover = acetone

wd-40 cuts any type of tar like gunk
