1.5 hrs cleaning the fuel tank parts with Extreme Simple Green solution.  I've started videoing all the steps of the fuel tank build, and I'm hoping to have that done in about a week (Keep in mind I'm an optimist...).

Next up will be cleaning the mating surfaces with MEK, abrading them with ScotchBrite and then re-cleaning with MEK.  Then the fun begins with the Prosealing...  MEK is really nasty stuff so I'll only do that outside with my P100 Class respirator firmly attached...
