Baz is right on.
It's probably simply a matter of not spending enough time on each step. Sanding and polishing is easy...knowing when to stop is not. You really need to use bright lighting at different angles to _see_ if you're getting the previous scratches out. Looking and seeing are two different things.
Are you using different wheels for the different compounds? Raking the wheels during polishing? Cleaning the metal between steps?
One possible problem is the 80 grit. When I started out I used 80 for the initial smoothing because it was fast. I soon discovered that it took far longer to get out the 80-grit scratches than the time it saved me. Now I never go lower than 120 to start - sometimes 220 if possible.
Also try skipping the tripoli. Sometimes it seems to me to be unhelpful, although some people swear by it.
