I would suggest belly bands also. It can be used one of two ways:
-Used as a quick fix. Put it on your boy and no matter how hard he tries nothing will be marked with his scent because everything is trapped on the belly band. Downside, it's up to you to keep him clean, (change the pad on the belly band, keep the belly band from smelling to discourage the marking, etc) and it's just a band aid.

-OR-

-Used in combination with training to eventually not need the belly band anymore. What I did is use a correction (double clap followed by a firm no) to discourage his leg lifting inside the house. When using the correction with the belly band makes things less stressful for you and for your pup. No matter how quick you and how vigilant you are they can still shoot out a drop of pee that will later intice them to keep marking. It's worked with my boy, he doesn't dare try to mark inside the house anymore.
He does have an excited pee reaction though, and even that is getting better. He sees me come home from work, the grocery store, or where ever that he couldn't come with me and he pees. He doesn't do it intentionally, he's just really emotional and excited and well...
Before I would try to correct him or get upset myself about always having to clean up pee. Which I know he felt and that just made things worse. It ended up being a vicious cycle of bad emotions. So now I put a belly band on him. I don't see the pee, I don't get upset and neither does he. He's still relatively new to my home, I've had him a little over a month. Combine a new home, new people, and the neuter (which I've been told can cause set backs in training) can be the root of your problem. I've seen progress and Kaji is less emotional about me leaving. He's gone from full on pee in his belly band to a squirt. I think it's progress and I hope eventually he won't have a need for belly bands at all.
Sorry for a long post, but I wanted to make sure I explained myself as best as I could.
