Correcting Poly-Brush mistake

I applied the first coat of Poly-Brush on a little more than half of my
fuselage (experimental homebuilt) before I realized I had not stirred the
can of Poly-Brush before using. Once the contents from the bottom were
stirred up the coating was definitely a darker shade of pink. Is this going
to be a problem? If so, should I perhaps spray an extra Poly-Brush coat
when the time comes? I suspect applying a second brush coat would leave
visible brush marks.
