When trying to overspray the PVA with a very dilute solution, we find it fish-eyes and no amount of brush-work puts it right.
Peel it off, wash it off, and start again
I could have gone for leaving the matte finish from the original PVA I laid down but then that would have negated all the benefits of using the really nice shiny plastic. Only option is to clean it all off and start again. If I was to go with a matte finish, it would mean lots of time spent polishing parts rather than letting the part material do the work for me.
