Stop in for a cup of coffee

I might get ambitious and fix my tub faucet today. Been leaking for a long time. Picked up a kit with the 3 valves and new handles a couple weeks ago.
What do you think of those cartridge faucets I have one I changed twice and it still drips, did the non hardening silicone lube on it looked at it for burs nothing seems to take care of it.
