polyester resin over vinylester resin

[holorinhal]

Can You laminate with polyester resin over fresh vinylester resin,without any complications.
I have some vinylester laminating resin left and a couple gallons of polyester,and am going to glass in the intake hole prior to doing a setback pump.
I wanted to start out with the vinylester laminating resin and finnish with the polly,if there are no ill effects!
Any thoughts on this from the glass guru's would be appreciated....Hal

My understanding is you can, but shouldn't.
