Super Shene with Airbrush

[Zonker1972]

I was finishing off a new motorcycle seat yesterday. I assembled the seat before my final top coat. I finished the top of the seat with 10 coats of Eco-flow gloss super shene. When I went to add the super shene to the sides of the seat, i thought it would be easier to use my airbrush. I did 10 coats with the airbrush, undiluted super shene, at ~25psi. the top coat went on fine but it has a matt finish even through i used the same gloss super shene. 

Does anyone know why this happened?

thanks.

Was it shaken up before use? The sheen will definitely separate from the mix if it sits. Same with Polyurethane. I had to redo 2500sq feet of hardwood floors for that reason. Guys doing that part just opened the cans and applied it. No effort to mix. Wasn’t a minor difference either… I airbrush everything and never had that issue, but it reminded me of a lesson learned and employees fired.

That's a good point. I initially poured some shene into a cup. So. I guess i could have had separated.
