You're better off getting the hobby lacquer thinners and using the bulk Home Depot stuff for airbrush cleaning. That's somewhat counter to the usual advice... you can buy enamel thinner in bulk for one heck of a lot less than a Testors Label can, and it works every bit as well. The hobby grade lacquer thinners, though, seem a bit less hot than the store can, and if you go with Mr Leveling Thinner it also comes with a retarder.
You don't need any thinner for MM Metalizers or Alclad. They're thinned for spraying right out of the bottle. If anything alclad's a bit thin. You go through a lot of it to get a good shiny coat down, but the results are fantastic if you follow the proper prep. You can clean the AB with the pricey Alclad Airbrush Cleaner, but $5 Quick Klean from HD works just as well.
For Mr Surfacer, I love using the 1200 for primer, but never got any control with the aerosol can. Get a bottle of 1200 or Mr Base White 1000 and thin it down 2-1 with Mr Leveling Thinner, and you'll have an awesome primer coat that can be sanded to baby bottom smoothness. Not sure it's any better than Tamiya Fine Surface Primer, though, which many on this forum love. I've just never used it.
