Hmmm……just tried spraying Tamiya X-22 Clear varnish and the stuff started frosting. I thought I’d nailed this problem…not good.
Edit; Well I managed to get the X-22 Clear varnish on using a Badger 200 rather than the Iwata CR although I was still getting some frosting. Next time I’ll add some acrylic retardent but the Badger 200 seemed to help. Also I was spraying that much I set off the smoke detector LOL. Oops! :o)
