Nice wheelie !

there is no easy way, its not going to "just wash off"

You would have to get it to melting point
Not sure what that is but ..I KNOW with a propane torch , it takes a minute or so before it softens
up , and it cools right back down

So, you can only do an area 6" x 6" maybe ?
and often it leaves a residue that you have to clean off with a rag soaked in ..

Its a PITA ..
how fancy is this beast going to be ?

The lips of fools bring them strife, and their mouths invite a beating.Proverbs 18:6
