.8mm needle for an Iwata Rev CR brush?

[b.still]

I have been told to find an .8mm needle and larger tip for my Iwata Revolution CR brush in order to use a TAT paint I recently purchased. The brush comes (as you probably know) with a .5mm needle and small tip. I can't seem to find these parts - I thought this brush required the needle size it came with?! Somebody please help - thanks in advance.

What line of tat paint are you using? To require a 0.8mm needle/nozzle, it must be like gravel, or a heavy paste.
If there are larger sizes available for the Revolution brushes, you would be able to find out for sure through Iwata themselves, but you may get a faster answer through Dixie, Coastairbrush, or someone of that nature.
