Hi Jake,

As mentioned, you can use and mix the KlassKote paints as they are the same. I would advise against mixing colors though as the tint may be slightly off if your plane has already been partially painted. Primer, catalysts, etc. are fine but I'd make sure of the colors expecially the bright ones. I have a bunch of the K&B at home so I'll check tonight.

FYI though, Frank Tiano has a LARGE stock of the K&B items and would not be a bad idea to call FTE. I have in the past and found everything I needed.

Hope this helps.

Adil
