It was a mess and the cuts were rough. Adding a drop of oil makes the tool glide smoothly and gives clean lines. Now I always keep a small bottle in my toolkit.
Honestly, the whole mix ratio thing reminds me of my grandpa trying to wash his car. He'd use about a gallon of soap and a trickle of water, the whole driveway was just a mountain of suds. Couldn't see the paint for ten minutes. I guess some people just really commit to the soap part.
