naw, you're supposed to scrape it till no more shavings come off. the purpose of the heating is heat the wax into the base, the rest is excess. 1/2 a bar is a bit much man. not sure what size board you have, but on my 155 i usually only use 1/4 bar of swix or tokyo wax. doesn't need to have a huge layer of wax!
sounds like you did a good job though! maybe just double check to make sure you got everything near the edges, my first couple of times i waxed i didn't get close enough to the edges..
