In-Wing Kreem Slosh removal method?

[wildirishtime]

I surprisingly can't find any threads detailing exactly the process
used for removing old Kreem from 2000 vintage tanks that are already
in the wing.

The general theory is discussed here and there in various threads, but
no clear procedure is outlined - specifically the threads don't discuss
how MUCH of the Kreem actually comes OUT in the process - all of it in
liquid form (like Kreem says)? or just that which is no longer bonded
perfectly? or just part of it ? Some people say use Acetone (including
Kreem themselves) some say use MEK...

Lastly, what do you guys do after rinsing/removing the Kreem on
the 'old' tanks? Re-slosh with the Caswell epoxy? Or maybe the Hirsch
product? Or is the 'rinse' removal enough if I don't really plan to run
E10 ( I'm a non-eth kinda guy!)?

Thanks!
