Airbrushing Gunze Sanyo Mr Primer 500/ 1000

hey,
Anyone knows how to prepare Mr Primer (bottle type) to be airbrushed? What's the thinner we should use to thin Mr Primer (bottles type) before airbrushing them? i tried to sprayed them direct unthin but they get clogged in the ab. Even after i thinned them with nitrocellolose thinner 50% they would get clogged fast. can i add Mr. Retarder to it? New techniques are always much appreciated.

yia.
