Question 1 : which should i use to clean my gun after spraying urethane ?
Acetone or Laquer thinner??
Question 2 : Are the little baggie things that go inside the siphon cup for easy clean-up a good idea or not...

I am a first time painter getting ready to experiment with a urethane i got off the internet from the Kustom Shop called Hot Rod Flatz. It is pre-flattened and ready to shoot. I thought since my son likes the old school flat black rod look, this would hold up better than black primer...Oh well we will see
Thanks for any help !!

 

I vote lacquer thinner, never tried acetone though.

 

i use lacquer thinner..

 

Laquer thinner, depending on the quality of the gun, I take it all apart and clean it. But if it's just a under 100$ gun, clean the bowl, tip, run laquer thinner through it with the tip on, and off, and leave the tip in the bowl with laquer thinner.
