I have a Paasche VL and I do exactly as madda suggested... pipecleaner. More precisely, I do this:
1. Flush and back-flush with thinner.
2. Remove needle
3. Use thinner soaked q-tip to clean out the intake (where you put the jar or color cup).
4. Remove the cap and tip and soak them in thinner.
5. Run a thinner soaked pipe cleaner down the pipe. If you only get about an inch or two of the pipe cleaner soaked, the rest of it will act as a bit of a dryer as you pull it through...)
6. Clean tip and cap with q-tip and/or pipe cleaner
7. Clean color cup (I find this to be the hardest thing to clean....)
Enjoy!!
