Good morning Chuck... Have you tried future thinned with lacquer thinner(leveling thinner for me) ?? Yes it can be thinned with lacquer thinner!!!
Thinned 70/30 favour to thinner... I tried it on my f-86 with Light passes....just to cover the decals...In my case it did not cut the shine I wanted... But again I want it a slightly dull NMF!!
As for AK Interactive Gauzy, it is nice, May be does not dull the metal finish But it is like you put a glass over the model... Did not like it... My humple opinion!
