The only big thing to watch for is that you don't put so much liquid in that you hydrolock your motor. I've never heard of anyone doing this - would probably take most or all of the can being dumped in at one time - but it's worth being aware of.
Also, plan your foaming. I didn't really think about where I was going to drive to get the smoke out last time I did my car. I live in a not-so-upscale neighborhood where crappy cars abound. As I was spewing out smoke, I got pulled over. No ticket or anything, but an embarrassing conversation involving lies and playing dumb that could have been avoided.
After blowing out a ton of smoke at idle (with some revving) you'll need to hit the highway for the second phase of foaming. Plan for five miles of smoking at speed.
