Gotta agree with rowings,
The Touch'n'Flow is great, but seems Deluxe Materials has made a copy with a replacable tip! Its called a " Pin Flow Applicator " and a demo can be found on YouTube:

They've separated the glass pipette from the tips, & I've yet to acquire one, locals don't have it in stock yet. Its also higher priced, $8 for a T'n'F (locally) where the PinFlow is $13. Anyone got one/tried it?
But for fine application of solvent glues, ditch the brush, use the T'n'F or Pinflow... 'cause it flows the solvent right into a seam. Once you've used one, odds are, you'll never go back.
