Like a year ago a shop was out of normal wax and I had to buy "chronic green". Looked f**king gay on day one (90's gay, not 2013 gay, it's cool). Still, a year later, the board looks like crap because the wax, even after a year of adding normal wax, still has green streaks in it. I recommend getting some of that firewater stuff, it's pricey, and purge your board of that hideous sh*t before it ruins your life entirely.
I don't even want to talk about sticky bumps punt wax... "Something I wish we could un-invent", as Nicholas Cage would put it.
Of course!!!!!!!!!! What I do is I just leave my board on my porch in the sun until it heats up and gets melty, then I simply scrape it off with a wax comb. The only time I really ever do this though is if my wax is getting old on the board, or the changing water temps for different wax.
